 1. Make sure that any feature branches you want have been merged.
-2. Pull in new translations and verify they are valid::
+
+2. Make a fresh branch for your release::
+
+    git flow release start $VERSION
+
+3. Extract strings for translation and push them to transifex::
+
+    pybabel extract -o po/kitchen.pot kitchen2 kitchen3
+    tx push -s
+    git commit -m 'Extract new strings from the source files' po/kitchen.pot

+
+* kitchen gained support for python3.  The tarball release now includes a
+  ``kitchen2/`` and a ``kitchen3/`` directory containing copies of the source
+  code modified to work against each of the two major python versions.  When
+  installing with ``pip`` or ``setup.py``, the appropriate version should be
+  selected and installed.
+* The canonical upstream repository location moved to git and github.  See
+  https://github.com/fedora-infra/kitchen
+* Added kitchen.text.misc.isbasestring(), kitchen.text.misc.isbytestring(),
+  and kitchen.text.misc.isunicodestring().  These are mainly useful for code
+  being ported to python3 as python3 lacks a basestring type and has two types
+  for byte strings.  Code that has to run on both python2 and python3 or
+  wants to provide similar byte vs unicode semantics may find these functions
+  to be a good abstraction.
+* Add a python2_api parameter to various i18n functions: NullTranslations
+  constructor, NewGNUTranslations constructor, and get_translation_object.
+  When set to True (the default), the python2 api for gettext objects is used.
+  When set to False, the python3 api is used.  This option is intended to aid
+  in porting from python2 to python3.
+* Exception messages are no longer translated.  The idea is that exceptions
+  should be easily searched for via a web search.
+* Fix a bug in unicode_to_xml() where xmlcharrefs created when a unicode
+  string is turned into a byte string with an encoding that doesn't have 
+  all of the needed characters had their ampersands ("&") escaped.
+* Fix a bug in NewGNUTranslations.lngettext() if a fallback gettext object is
+  used and the message is not in any catalog.
+* Speedups to process_control_chars() that are directly reflected in
+  unicode_to_xml() and byte_string_to_xml()
+* Remove C1 Control Codes in to_xml() as well as C0 Control Codes

+Translation Objects
+===================
+
+The standard translation objects from the :mod:`gettext` module suffer from
+several problems:
+
+* They can throw :exc:`UnicodeError`
+* They can't find translations for non-:term:`ASCII` byte :class:`str`
+  messages
+* They may return either :class:`unicode` string or byte :class:`str` from the
+  same function even though the functions say they will only return
+  :class:`unicode` or only return byte :class:`str`.
+
+:class:`DummyTranslations` and :class:`NewGNUTranslations` were written to fix
+these issues.

+
+Byte Strings and Unicode in Python2
+===================================
+
+Python2 has two string types, :class:`str` and :class:`unicode`.
+:class:`unicode` represents an abstract sequence of text characters.  It can
+hold any character that is present in the unicode standard.  :class:`str` can
+hold any byte of data.  The operating system and python work together to
+display these bytes as characters in many cases but you should always keep in
+mind that the information is really a sequence of bytes, not a sequence of
+characters.  In python2 these types are interchangeable a large amount of the
+time.  They are one of the few pairs of types that automatically convert when
+used in equality::
+
+    >>> # string is converted to unicode and then compared
+    >>> "I am a string" == u"I am a string"
+    True
+    >>> # Other types, like int, don't have this special treatment
+    >>> 5 == "5"
+    False
+
+However, this automatic conversion tends to lull people into a false sense of
+security.  As long as you're dealing with :term:`ASCII` characters the
+automatic conversion will save you from seeing any differences.  Once you
+start using characters that are not in :term:`ASCII`, you will start getting
+:exc:`UnicodeError` and :exc:`UnicodeWarning` as the automatic conversions
+between the types fail::
+
+    >>> "I am an ñ" == u"I am an ñ"
+    __main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
+    False
+
+Why do these conversions fail?  The reason is that the python2
+:class:`unicode` type represents an abstract sequence of unicode text known as
+:term:`code points`.  :class:`str`, on the other hand, really represents
+a sequence of bytes.  Those bytes are converted by your operating system to
+appear as characters on your screen using a particular encoding (usually
+with a default defined by the operating system and customizable by the
+individual user.) Although :term:`ASCII` characters are fairly standard in
+what bytes represent each character, the bytes outside of the :term:`ASCII`
+range are not.  In general, each encoding will map a different character to
+a particular byte.  Newer encodings map individual characters to multiple
+bytes (which the older encodings will instead treat as multiple characters).
+In the face of these differences, python refuses to guess at an encoding and
+instead issues a warning or exception and refuses to convert.
+
+.. seealso::
+    :ref:`overcoming-frustration`
+        For a longer introduction on this subject.
+
+Strategy for Explicit Conversion
+================================
+
+So what is the best method of dealing with this weltering babble of incoherent
+encodings?  The basic strategy is to explicitly turn everything into
+:class:`unicode` when it first enters your program.  Then, when you send it to
+output, you can transform the unicode back into bytes.  Doing this allows you
+to control the encodings that are used and avoid getting tracebacks due to
+:exc:`UnicodeError`. Using the functions defined in this module, that looks
+something like this:
+
+.. code-block:: pycon
+    :linenos:
+
+    >>> from kitchen.text.converters import to_unicode, to_bytes
+    >>> name = raw_input('Enter your name: ')
+    Enter your name: Toshio くらとみ
+    >>> name
+    'Toshio \xe3\x81\x8f\xe3\x82\x89\xe3\x81\xa8\xe3\x81\xbf'
+    >>> type(name)
+    <type 'str'>
+    >>> unicode_name = to_unicode(name)
+    >>> type(unicode_name)
+    <type 'unicode'>
+    >>> unicode_name
+    u'Toshio \u304f\u3089\u3068\u307f'
+    >>> # Do a lot of other things before needing to save/output again:
+    >>> output = open('datafile', 'w')
+    >>> output.write(to_bytes(u'Name: %s\\n' % unicode_name))
+
+A few notes:
+
+Looking at line 6, you'll notice that the input we took from the user was
+a byte :class:`str`.  In general, anytime we're getting a value from outside
+of python (The filesystem, reading data from the network, interacting with an
+external command, reading values from the environment) we are interacting with
+something that will want to give us a byte :class:`str`.  Some |stdlib|_
+modules and third party libraries will automatically attempt to convert a byte
+:class:`str` to :class:`unicode` strings for you.  This is both a boon and
+a curse.  If the library can guess correctly about the encoding that the data
+is in, it will return :class:`unicode` objects to you without you having to
+convert.  However, if it can't guess correctly, you may end up with one of
+several problems:
+
+:exc:`UnicodeError`
+    The library attempted to decode a byte :class:`str` into
+    a :class:`unicode`, string failed, and raises an exception.
+Garbled data
+    If the library returns the data after decoding it with the wrong encoding,
+    the characters you see in the :exc:`unicode` string won't be the ones that
+    you expect.
+A byte :class:`str` instead of :class:`unicode` string
+    Some libraries will return a :class:`unicode` string when they're able to
+    decode the data and a byte :class:`str`  when they can't.  This is
+    generally the hardest problem to debug when it occurs.  Avoid it in your
+    own code and try to avoid or open bugs against upstreams that do this. See
+    :ref:`DesigningUnicodeAwareAPIs` for strategies to do this properly.
+
+On line 8, we convert from a byte :class:`str` to a :class:`unicode` string.
+:func:`~kitchen.text.converters.to_unicode` does this for us.  It has some
+error handling and sane defaults that make this a nicer function to use than
+calling :meth:`str.decode` directly:
+
+* Instead of defaulting to the :term:`ASCII` encoding which fails with all
+  but the simple American English characters, it defaults to :term:`UTF-8`.
+* Instead of raising an error if it cannot decode a value, it will replace
+  the value with the unicode "Replacement character" symbol (``<EFBFBD>``).
+* If you happen to call this method with something that is not a :class:`str`
+  or :class:`unicode`, it will return an empty :class:`unicode` string.
+
+All three of these can be overridden using different keyword arguments to the
+function.  See the :func:`to_unicode` documentation for more information.
+
+On line 15 we push the data back out to a file.  Two things you should note here:
+
+1. We deal with the strings as :class:`unicode` until the last instant.  The
+   string format that we're using is :class:`unicode` and the variable also
+   holds :class:`unicode`.  People sometimes get into trouble when they mix
+   a byte :class:`str` format with a variable that holds a :class:`unicode`
+   string (or vice versa) at this stage.
+2. :func:`~kitchen.text.converters.to_bytes`, does the reverse of
+   :func:`to_unicode`.  In this case, we're using the default values which
+   turn :class:`unicode` into a byte :class:`str` using :term:`UTF-8`.  Any
+   errors are replaced with a ``<EFBFBD>`` and sending nonstring objects yield empty
+   :class:`unicode` strings.  Just like :func:`to_unicode`, you can look at
+   the documentation for :func:`to_bytes` to find out how to override any of
+   these defaults.
+
+When to use an alternate strategy
+---------------------------------
+
+The default strategy of decoding to :class:`unicode` strings when you take
+data in and encoding to a byte :class:`str` when you send the data back out
+works great for most problems but there are a few times when you shouldn't:
+
+* The values aren't meant to be read as text
+* The values need to be byte-for-byte when you send them back out -- for
+  instance if they are database keys or filenames.
+* You are transferring the data between several libraries that all expect
+  byte :class:`str`.
+
+In each of these instances, there is a reason to keep around the byte
+:class:`str` version of a value.  Here's a few hints to keep your sanity in
+these situations:
+
+1. Keep your :class:`unicode` and :class:`str` values separate.  Just like the
+   pain caused when you have to use someone else's library that returns both
+   :class:`unicode` and :class:`str` you can cause yourself pain if you have
+   functions that can return both types or variables that could hold either
+   type of value.
+2. Name your variables so that you can tell whether you're storing byte
+   :class:`str` or :class:`unicode` string.  One of the first things you end
+   up having to do when debugging is determine what type of string you have in
+   a variable and what type of string you are expecting.  Naming your
+   variables consistently so that you can tell which type they are supposed to
+   hold will save you from at least one of those steps.
+3. When you get values initially, make sure that you're dealing with the type
+   of value that you expect as you save it.  You can use :func:`isinstance`
+   or :func:`to_bytes` since :func:`to_bytes` doesn't do any modifications of
+   the string if it's already a :class:`str`.  When using :func:`to_bytes`
+   for this purpose you might want to use::
+
+        try:
+            b_input = to_bytes(input_should_be_bytes_already, errors='strict', nonstring='strict')
+        except:
+            handle_errors_somehow()
+
+   The reason is that the default of :func:`to_bytes` will take characters
+   that are illegal in the chosen encoding and transform them to replacement
+   characters.  Since the point of keeping this data as a byte :class:`str` is
+   to keep the exact same bytes when you send it outside of your code,
+   changing things to replacement characters should be rasing red flags that
+   something is wrong.  Setting :attr:`errors` to ``strict`` will raise an
+   exception which gives you an opportunity to fail gracefully.
+4. Sometimes you will want to print out the values that you have in your byte
+   :class:`str`.  When you do this you will need to make sure that you
+   transform :class:`unicode` to :class:`str` before combining them.  Also be
+   sure that any other function calls (including :mod:`gettext`) are going to
+   give you strings that are the same type.  For instance::
+
+        print to_bytes(_('Username: %(user)s'), 'utf-8') % {'user': b_username}
+
+Gotchas and how to avoid them
+=============================
+
+Even when you have a good conceptual understanding of how python2 treats
+:class:`unicode` and :class:`str` there are still some things that can
+surprise you.  In most cases this is because, as noted earlier, python or one
+of the python libraries you depend on is trying to convert a value
+automatically and failing.  Explicit conversion at the appropriate place
+usually solves that.
+
+str(obj)
+--------
+
+One common idiom for getting a simple, string representation of an object is to use::
+
+    str(obj)
+
+Unfortunately, this is not safe.  Sometimes str(obj) will return
+:class:`unicode`.  Sometimes it will return a byte :class:`str`.  Sometimes,
+it will attempt to convert from a :class:`unicode` string to a byte
+:class:`str`, fail, and throw a :exc:`UnicodeError`.  To be safe from all of
+these, first decide whether you need :class:`unicode` or :class:`str` to be
+returned.  Then use :func:`to_unicode` or :func:`to_bytes` to get the simple
+representation like this::
+
+    u_representation = to_unicode(obj, nonstring='simplerepr')
+    b_representation = to_bytes(obj, nonstring='simplerepr')
+
+print
+-----
+
+python has a builtin :func:`print` statement that outputs strings to the
+terminal.  This originated in a time when python only dealt with byte
+:class:`str`.  When :class:`unicode` strings came about, some enhancements
+were made to the :func:`print` statement so that it could print those as well.
+The enhancements make :func:`print` work most of the time.  However, the times
+when it doesn't work tend to make for cryptic debugging.
+
+The basic issue is that :func:`print` has to figure out what encoding to use
+when it prints a :class:`unicode` string to the terminal.  When python is
+attached to your terminal (ie, you're running the interpreter or running
+a script that prints to the screen) python is able to take the encoding value
+from your locale settings :envvar:`LC_ALL` or :envvar:`LC_CTYPE` and print the
+characters allowed by that encoding.  On most modern Unix systems, the
+encoding is :term:`utf-8` which means that you can print any :class:`unicode`
+character without problem.
+
+There are two common cases of things going wrong:
+
+1. Someone has a locale set that does not accept all valid unicode characters.
+   For instance::
+
+        $ LC_ALL=C python
+        >>> print u'\ufffd'
+        Traceback (most recent call last):
+          File "<stdin>", line 1, in <module>
+        UnicodeEncodeError: 'ascii' codec can't encode character u'\ufffd' in position 0: ordinal not in range(128)
+
+   This often happens when a script that you've written and debugged from the
+   terminal is run from an automated environment like :program:`cron`.  It
+   also occurs when you have written a script using a :term:`utf-8` aware
+   locale and released it for consumption by people all over the internet.
+   Inevitably, someone is running with a locale that can't handle all unicode
+   characters and you get a traceback reported.
+2. You redirect output to a file.  Python isn't using the values in
+   :envvar:`LC_ALL` unconditionally to decide what encoding to use.  Instead
+   it is using the encoding set for the terminal you are printing to which is
+   set to accept different encodings by :envvar:`LC_ALL`.  If you redirect
+   to a file, you are no longer printing to the terminal so :envvar:`LC_ALL`
+   won't have any effect.  At this point, python will decide it can't find an
+   encoding and fallback to :term:`ASCII` which will likely lead to
+   :exc:`UnicodeError` being raised.  You can see this in a short script::
+
+        #! /usr/bin/python -tt
+        print u'\ufffd'
+
+   And then look at the difference between running it normally and redirecting to a file:
+
+   .. code-block:: console
+
+        $ ./test.py
+        <20>
+        $ ./test.py > t
+        Traceback (most recent call last):
+          File "test.py", line 3, in <module>
+              print u'\ufffd'
+        UnicodeEncodeError: 'ascii' codec can't encode character u'\ufffd' in position 0: ordinal not in range(128)
+
+The short answer to dealing with this is to always use bytes when writing
+output.  You can do this by explicitly converting to bytes like this::
+
+    from kitchen.text.converters import to_bytes
+    u_string = u'\ufffd'
+    print to_bytes(u_string)
+
+or you can wrap stdout and stderr with a :class:`~codecs.StreamWriter`.
+A :class:`~codecs.StreamWriter` is convenient in that you can assign it to
+encode for :data:`sys.stdout` or :data:`sys.stderr` and then have output
+automatically converted but it has the drawback of still being able to throw
+:exc:`UnicodeError` if the writer can't encode all possible unicode
+codepoints.  Kitchen provides an alternate version which can be retrieved with
+:func:`kitchen.text.converters.getwriter` which will not traceback in its
+standard configuration.
+
+.. _unicode-and-dict-keys:
+
+Unicode, str, and dict keys
+---------------------------
+
+The :func:`hash` of the :term:`ASCII` characters is the same for
+:class:`unicode` and byte :class:`str`.  When you use them in :class:`dict`
+keys, they evaluate to the same dictionary slot::
+
+    >>> u_string = u'a'
+    >>> b_string = 'a'
+    >>> hash(u_string), hash(b_string)
+    (12416037344, 12416037344)
+    >>> d = {}
+    >>> d[u_string] = 'unicode'
+    >>> d[b_string] = 'bytes'
+    >>> d
+    {u'a': 'bytes'}
+
+When you deal with key values outside of :term:`ASCII`, :class:`unicode` and
+byte :class:`str` evaluate unequally no matter what their character content or
+hash value::
+
+    >>> u_string = u'ñ'
+    >>> b_string = u_string.encode('utf-8')
+    >>> print u_string
+    ñ
+    >>> print b_string
+    ñ
+    >>> d = {}
+    >>> d[u_string] = 'unicode'
+    >>> d[b_string] = 'bytes'
+    >>> d
+    {u'\\xf1': 'unicode', '\\xc3\\xb1': 'bytes'}
+    >>> b_string2 = '\\xf1'
+    >>> hash(u_string), hash(b_string2)
+    (30848092528, 30848092528)
+    >>> d = {}
+    >>> d[u_string] = 'unicode'
+    >>> d[b_string2] = 'bytes'
+    {u'\\xf1': 'unicode', '\\xf1': 'bytes'}
+
+How do you work with this one?  Remember rule #1:  Keep your :class:`unicode`
+and byte :class:`str` values separate.  That goes for keys in a dictionary
+just like anything else.
+
+* For any given dictionary, make sure that all your keys are either
+  :class:`unicode` or :class:`str`.  **Do not mix the two.**  If you're being
+  given both :class:`unicode` and :class:`str` but you don't need to preserve
+  separate keys for each, I recommend using :func:`to_unicode` or
+  :func:`to_bytes` to convert all keys to one type or the other like this::
+
+        >>> from kitchen.text.converters import to_unicode
+        >>> u_string = u'one'
+        >>> b_string = 'two'
+        >>> d = {}
+        >>> d[to_unicode(u_string)] = 1
+        >>> d[to_unicode(b_string)] = 2
+        >>> d
+        {u'two': 2, u'one': 1}
+
+* These issues also apply to using dicts with tuple keys that contain
+  a mixture of :class:`unicode` and :class:`str`.  Once again the best fix
+  is to standardise on either :class:`str` or :class:`unicode`.
+
+* If you absolutely need to store values in a dictionary where the keys could
+  be either :class:`unicode` or :class:`str` you can use
+  :class:`~kitchen.collections.strictdict.StrictDict` which has separate
+  entries for all :class:`unicode` and byte :class:`str` and deals correctly
+  with any :class:`tuple` containing mixed :class:`unicode` and byte
+  :class:`str`.

+
+============================
+Designing Unicode Aware APIs
+============================
+
+APIs that deal with byte :class:`str` and :class:`unicode` strings are
+difficult to get right.  Here are a few strategies with pros and cons of each.
+
+.. contents::
+
+-------------------------------------------------
+Take either bytes or unicode, output only unicode
+-------------------------------------------------
+
+In this strategy, you allow the user to enter either :class:`unicode` strings
+or byte :class:`str` but what you give back is always :class:`unicode`.  This
+strategy is easy for novice endusers to start using immediately as they will
+be able to feed either type of string into the function and get back a string
+that they can use in other places.
+
+However, it does lead to the novice writing code that functions correctly when
+testing it with :term:`ASCII`-only data but fails when given data that contains
+non-:term:`ASCII` characters.  Worse, if your API is not designed to be
+flexible, the consumer of your code won't be able to easily correct those
+problems once they find them.
+
+Here's a good API that uses this strategy::
+
+    from kitchen.text.converters import to_unicode
+
+    def truncate(msg, max_length, encoding='utf8', errors='replace'):
+        msg = to_unicode(msg, encoding, errors)
+        return msg[:max_length]
+
+The call to :func:`truncate` starts with the essential parameters for
+performing the task.  It ends with two optional keyword arguments that define
+the encoding to use to transform from a byte :class:`str` to :class:`unicode`
+and the strategy to use if undecodable bytes are encountered.  The defaults
+may vary depending on the use cases you have in mind.  When the output is
+generally going to be printed for the user to see, ``errors='replace'`` is
+a good default.  If you are constructing keys to a database, raisng an
+exception (with ``errors='strict'``) may be a better default.  In either case,
+having both parameters allows the person using your API to choose how they
+want to handle any problems.  Having the values is also a clue to them that
+a conversion from byte :class:`str` to :class:`unicode` string is going to
+occur.
+
+.. note::
+
+    If you're targeting python-3.1 and above, ``errors='surrogateescape'`` may
+    be a better default than ``errors='strict'``.  You need to be mindful of
+    a few things when using ``surrogateescape`` though:
+
+    * ``surrogateescape`` will cause issues if a non-:term:`ASCII` compatible
+      encoding is used (for instance, UTF-16 and UTF-32.)  That makes it
+      unhelpful in situations where a true general purpose method of encoding
+      must be found.  :pep:`383` mentions that ``surrogateescape`` was
+      specifically designed with the limitations of translating using system
+      locales (where :term:`ASCII` compatibility is generally seen as
+      inescapable) so you should keep that in mind.
+    * If you use ``surrogateescape`` to decode from :class:`bytes`
+      to :class:`unicode` you will need to use an error handler other than
+      ``strict`` to encode as the lone surrogate that this error handler
+      creates makes for invalid unicode that must be handled when encoding.
+      In Python-3.1.2 or less, a bug in the encoder error handlers mean that
+      you can only use ``surrogateescape`` to encode; anything else will throw
+      an error.
+
+    Evaluate your usages of the variables in question to see what makes sense.
+
+Here's a bad example of using this strategy::
+
+    from kitchen.text.converters import to_unicode
+
+    def truncate(msg, max_length):
+        msg = to_unicode(msg)
+        return msg[:max_length]
+
+In this example, we don't have the optional keyword arguments for
+:attr:`encoding` and :attr:`errors`.  A user who uses this function is more
+likely to miss the fact that a conversion from byte :class:`str` to
+:class:`unicode` is going to occur.  And once an error is reported, they will
+have to look through their backtrace and think harder about where they want to
+transform their data into :class:`unicode` strings instead of having the
+opportunity to control how the conversion takes place in the function itself.
+Note that the user does have the ability to make this work by making the
+transformation to unicode themselves::
+
+    from kitchen.text.converters import to_unicode
+
+    msg = to_unicode(msg, encoding='euc_jp', errors='ignore')
+    new_msg = truncate(msg, 5)
+
+--------------------------------------------------
+Take either bytes or unicode, output the same type
+--------------------------------------------------
+
+This strategy is sometimes called polymorphic because the type of data that is
+returned is dependent on the type of data that is received.  The concept is
+that when you are given a byte :class:`str` to process, you return a byte
+:class:`str` in your output.  When you are given :class:`unicode` strings to
+process, you return :class:`unicode` strings in your output.
+
+This can work well for end users as the ones that know about the difference
+between the two string types will already have transformed the strings to
+their desired type before giving it to this function.  The ones that don't can
+remain blissfully ignorant (at least, as far as your function is concerned) as
+the function does not change the type.
+
+In cases where the encoding of the byte :class:`str` is known or can be
+discovered based on the input data this works well.  If you can't figure out
+the input encoding, however, this strategy can fail in any of the following
+cases:
+
+1. It needs to do an internal conversion between byte :class:`str` and
+   :class:`unicode` string.
+2. It cannot return the same data as either a :class:`unicode` string or byte
+   :class:`str`.
+3. You may need to deal with byte strings that are not byte-compatible with
+   :term:`ASCII`
+
+First, a couple examples of using this strategy in a good way::
+
+    def translate(msg, table):
+        replacements = table.keys()
+        new_msg = []
+        for index, char in enumerate(msg):
+            if char in replacements:
+                new_msg.append(table[char])
+            else:
+                new_msg.append(char)
+
+        return ''.join(new_msg)
+
+In this example, all of the strings that we use (except the empty string which
+is okay because it doesn't have any characters to encode) come from outside of
+the function.  Due to that, the user is responsible for making sure that the
+:attr:`msg`, and the keys and values in :attr:`table` all match in terms of
+type (:class:`unicode` vs :class:`str`) and encoding (You can do some error
+checking to make sure the user gave all the same type but you can't do the
+same for the user giving different encodings).  You do not need to make
+changes to the string that require you to know the encoding or type of the
+string; everything is a simple replacement of one element in the array of
+characters in message with the character in table.
+
+::
+
+    import json
+    from kitchen.text.converters import to_unicode, to_bytes
+
+    def first_field_from_json_data(json_string):
+        '''Return the first field in a json data structure.
+
+        The format of the json data is a simple list of strings.
+        '["one", "two", "three"]'
+        '''
+        if isinstance(json_string, unicode):
+            # On all python versions, json.loads() returns unicode if given
+            # a unicode string
+            return json.loads(json_string)[0]
+
+        # Byte str: figure out which encoding we're dealing with
+        if '\x00' not in json_data[:2]
+            encoding = 'utf8'
+        elif '\x00\x00\x00' == json_data[:3]:
+            encoding = 'utf-32-be'
+        elif '\x00\x00\x00' == json_data[1:4]:
+            encoding = 'utf-32-le'
+        elif '\x00' == json_data[0] and '\x00' == json_data[2]:
+            encoding = 'utf-16-be'
+        else:
+            encoding = 'utf-16-le'
+
+        data = json.loads(unicode(json_string, encoding))
+        return data[0].encode(encoding)
+
+In this example the function takes either a byte :class:`str` type or
+a :class:`unicode` string that has a list in json format and returns the first
+field from it as the type of the input string.  The first section of code is
+very straightforward; we receive a :class:`unicode` string, parse it with
+a function, and then return the first field from our parsed data (which our
+function returned to us as json data).
+
+The second portion that deals with byte :class:`str` is not so
+straightforward.  Before we can parse the string we have to determine what
+characters the bytes in the string map to.  If we didn't do that, we wouldn't
+be able to properly find which characters are present in the string.  In order
+to do that we have to figure out the encoding of the byte :class:`str`.
+Luckily, the json specification states that all strings are unicode and
+encoded with one of UTF32be, UTF32le, UTF16be, UTF16le, or :term:`UTF-8`.  It further
+defines the format such that the first two characters are always
+:term:`ASCII`.  Each of these has a different sequence of NULLs when they
+encode an :term:`ASCII` character.  We can use that to detect which encoding
+was used to create the byte :class:`str`.
+
+Finally, we return the byte :class:`str` by encoding the :class:`unicode` back
+to a byte :class:`str`.
+
+As you can see, in this example we have to convert from byte :class:`str` to
+:class:`unicode` and back.  But we know from the json specification that byte
+:class:`str` has to be one of a limited number of encodings that we are able
+to detect.  That ability makes this strategy work.
+
+Now for some examples of using this strategy in ways that fail::
+
+    import unicodedata
+    def first_char(msg):
+        '''Return the first character in a string'''
+        if not isinstance(msg, unicode):
+            try:
+                msg = unicode(msg, 'utf8')
+            except UnicodeError:
+                msg = unicode(msg, 'latin1')
+        msg = unicodedata.normalize('NFC', msg)
+        return msg[0]
+
+If you look at that code and think that there's something fragile and prone to
+breaking in the ``try: except:`` block you are correct in being suspicious.
+This code will fail on multi-byte character sets that aren't :term:`UTF-8`.  It
+can also fail on data where the sequence of bytes is valid :term:`UTF-8` but
+the bytes are actually of a different encoding.  The reasons this code fails
+is that we don't know what encoding the bytes are in and the code must convert
+from a byte :class:`str` to a :class:`unicode` string in order to function.
+
+In order to make this code robust we must know the encoding of :attr:`msg`.
+The only way to know that is to ask the user so the API must do that::
+
+    import unicodedata
+    def number_of_chars(msg, encoding='utf8', errors='strict'):
+        if not isinstance(msg, unicode):
+            msg = unicode(msg, encoding, errors)
+        msg = unicodedata.normalize('NFC', msg)
+        return len(msg)
+
+Another example of failure::
+
+    import os
+    def listdir(directory):
+        files = os.listdir(directory)
+        if isinstance(directory, str):
+            return files
+        # files could contain both bytes and unicode
+        new_files = []
+        for filename in files:
+            if not isinstance(filename, unicode):
+                # What to do here?
+                continue
+            new_files.appen(filename)
+        return new_files
+
+This function illustrates the second failure mode.  Here, not all of the
+possible values can be represented as :class:`unicode` without knowing more
+about the encoding of each of the filenames involved.  Since each filename
+could have a different encoding there's a few different options to pursue.  We
+could make this function always return byte :class:`str` since that can
+accurately represent anything that could be returned.  If we want to return
+:class:`unicode` we need to at least allow the user to specify what to do in
+case of an error decoding the bytes to :class:`unicode`.  We can also let the
+user specify the encoding to use for doing the decoding but that won't help in
+all cases since not all files will be in the same encoding (or even
+necessarily in any encoding)::
+
+    import locale
+    import os
+    def listdir(directory, encoding=locale.getpreferredencoding(), errors='strict'):
+        # Note: In python-3.1+, surrogateescape may be a better default
+        files = os.listdir(directory)
+        if isinstance(directory, str):
+            return files
+        new_files = []
+        for filename in files:
+            if not isinstance(filename, unicode):
+                filename = unicode(filename, encoding=encoding, errors=errors)
+            new_files.append(filename)
+        return new_files
+
+Note that although we use :attr:`errors` in this example as what to pass to
+the codec that decodes to :class:`unicode` we could also have an
+:attr:`errors` argument that decides other things to do like skip a filename
+entirely, return a placeholder (``Nondisplayable filename``), or raise an
+exception.
+
+This leaves us with one last failure to describe::
+
+    def first_field(csv_string):
+        '''Return the first field in a comma separated values string.'''
+        try:
+            return csv_string[:csv_string.index(',')]
+        except ValueError:
+            return csv_string
+
+This code looks simple enough.  The hidden error here is that we are searching
+for a comma character in a byte :class:`str` but not all encodings will use
+the same sequence of bytes to represent the comma.  If you use an encoding
+that's not :term:`ASCII` compatible on the byte level, then the literal comma
+``','`` in the above code will match inappropriate bytes.  Some examples of
+how it can fail:
+
+* Will find the byte representing an :term:`ASCII` comma in another character
+* Will find the comma but leave trailing garbage bytes on the end of the
+  string
+* Will not match the character that represents the comma in this encoding
+
+There are two ways to solve this.  You can either take the encoding value from
+the user or you can take the separator value from the user.  Of the two,
+taking the encoding is the better option for two reasons:
+
+1. Taking a separator argument doesn't clearly document for the API user that
+   the reason they must give it is to properly match the encoding of the
+   :attr:`csv_string`.  They're just as likely to think that it's simply a way
+   to specify an alternate character (like ":" or "|") for the separator.
+2. It's possible for a variable width encoding to reuse the same byte sequence
+   for different characters in multiple sequences.
+
+   .. note::
+
+        :term:`UTF-8` is resistant to this as any character's sequence of
+        bytes will never be a subset of another character's sequence of bytes.
+
+With that in mind, here's how to improve the API::
+
+    def first_field(csv_string, encoding='utf-8', errors='replace'):
+        if not isinstance(csv_string, unicode):
+            u_string = unicode(csv_string, encoding, errors)
+            is_unicode = False
+        else:
+            u_string = csv_string
+
+        try:
+            field = u_string[:U_string.index(u',')]
+        except ValueError:
+            return csv_string
+
+        if not is_unicode:
+            field = field.encode(encoding, errors)
+        return field
+
+.. note::
+
+    If you decide you'll never encounter a variable width encoding that reuses
+    byte sequences you can use this code instead::
+
+        def first_field(csv_string, encoding='utf-8'):
+            try:
+                return csv_string[:csv_string.index(','.encode(encoding))]
+            except ValueError:
+                return csv_string
+
+------------------
+Separate functions
+------------------
+
+Sometimes you want to be able to take either byte :class:`str` or
+:class:`unicode` strings, perform similar operations on either one and then
+return data in the same format as was given.  Probably the easiest way to do
+that is to have separate functions for each and adopt a naming convention to
+show that one is for working with byte :class:`str` and the other is for
+working with :class:`unicode` strings::
+
+    def translate_b(msg, table):
+        '''Replace values in str with other byte values like unicode.translate'''
+        if not isinstance(msg, str):
+            raise TypeError('msg must be of type str')
+        str_table = [chr(s) for s in xrange(0,256)]
+        delete_chars = []
+        for chr_val in (k for k in table.keys() if isinstance(k, int)):
+            if chr_val > 255:
+                raise ValueError('Keys in table must not exceed 255)')
+            if table[chr_val] == None:
+                delete_chars.append(chr(chr_val))
+            elif isinstance(table[chr_val], int):
+                if table[chr_val] > 255:
+                    raise TypeError('table values cannot be more than 255 or less than 0')
+                str_table[chr_val] = chr(table[chr_val])
+            else:
+                if not isinstance(table[chr_val], str):
+                    raise TypeError('character mapping must return integer, None or str')
+                str_table[chr_val] = table[chr_val]
+        str_table = ''.join(str_table)
+        delete_chars = ''.join(delete_chars)
+        return msg.translate(str_table, delete_chars)
+
+    def translate(msg, table):
+        '''Replace values in a unicode string with other values'''
+        if not isinstance(msg, unicode):
+            raise TypeError('msg must be of type unicode')
+        return msg.translate(table)
+
+There's several things that we have to do in this API:
+
+* Because the function names might not be enough of a clue to the user of the
+  functions of the value types that are expected, we have to check that the
+  types are correct.
+
+* We keep the behaviour of the two functions as close to the same as possible,
+  just with byte :class:`str` and :class:`unicode` strings substituted for
+  each other.
+
+
+-----------------------------------------------------------------
+Deciding whether to take str or unicode when no value is returned
+-----------------------------------------------------------------
+
+Not all functions have a return value.  Sometimes a function is there to
+interact with something external to python, for instance, writing a file out
+to disk or a method exists to update the internal state of a data structure.
+One of the main questions with these APIs is whether to take byte
+:class:`str`, :class:`unicode` string, or both.  The answer depends on your
+use case but I'll give some examples here.
+
+Writing to external data
+========================
+
+When your information is going to an external data source like writing to
+a file you need to decide whether to take in :class:`unicode` strings or byte
+:class:`str`.  Remember that most external data sources are not going to be
+dealing with unicode directly.  Instead, they're going to be dealing with
+a sequence of bytes that may be interpreted as unicode.  With that in mind,
+you either need to have the user give you a byte :class:`str` or convert to
+a byte :class:`str` inside the function.
+
+Next you need to think about the type of data that you're receiving.  If it's
+textual data, (for instance, this is a chat client and the user is typing
+messages that they expect to be read by another person) it probably makes sense to
+take in :class:`unicode` strings and do the conversion inside your function.
+On the other hand, if this is a lower level function that's passing data into
+a network socket, it probably should be taking byte :class:`str` instead.
+
+Just as noted in the API notes above, you should specify an :attr:`encoding`
+and :attr:`errors` argument if you need to transform from :class:`unicode`
+string to byte :class:`str` and you are unable to guess the encoding from the
+data itself.
+
+Updating data structures
+========================
+
+Sometimes your API is just going to update a data structure and not
+immediately output that data anywhere.  Just as when writing external data,
+you should think about both what your function is going to do with the data
+eventually and what the caller of your function is thinking that they're
+giving you.  Most of the time, you'll want to take :class:`unicode` strings
+and enter them into the data structure as :class:`unicode` when the data is
+textual in nature.  You'll want to take byte :class:`str` and enter them into
+the data structure as byte :class:`str` when the data is not text.  Use
+a naming convention so the user knows what's expected.
+
+-------------
+APIs to Avoid
+-------------
+
+There are a few APIs that are just wrong.  If you catch yourself making an API
+that does one of these things, change it before anyone sees your code.
+
+Returning unicode unless a conversion fails
+===========================================
+
+This type of API usually deals with byte :class:`str` at some point and
+converts it to :class:`unicode` because it's usually thought to be text.
+However, there are times when the bytes fail to convert to a :class:`unicode`
+string.  When that happens, this API returns the raw byte :class:`str` instead
+of a :class:`unicode` string.  One example of this is present in the |stdlib|_:
+python2's :func:`os.listdir`::
+
+    >>> import os
+    >>> import locale
+    >>> locale.getpreferredencoding()
+    'UTF-8'
+    >>> os.mkdir('/tmp/mine')
+    >>> os.chdir('/tmp/mine')
+    >>> open('nonsense_char_\xff', 'w').close()
+    >>> open('all_ascii', 'w').close()
+    >>> os.listdir(u'.')
+    [u'all_ascii', 'nonsense_char_\xff']
+
+The problem with APIs like this is that they cause failures that are hard to
+debug because they don't happen where the variables are set.  For instance,
+let's say you take the filenames from :func:`os.listdir` and give it to this
+function::
+
+    def normalize_filename(filename):
+        '''Change spaces and dashes into underscores'''
+        return filename.translate({ord(u' '):u'_', ord(u' '):u'_'})
+
+When you test this, you use filenames that all are decodable in your preferred
+encoding and everything seems to work.  But when this code is run on a machine
+that has filenames in multiple encodings the filenames returned by
+:func:`os.listdir` suddenly include byte :class:`str`.  And byte :class:`str`
+has a different :func:`string.translate` function that takes different values.
+So the code raises an exception where it's not immediately obvious that
+:func:`os.listdir` is at fault.
+
+Ignoring values with no chance of recovery
+==========================================
+
+An early version of python3 attempted to fix the :func:`os.listdir` problem
+pointed out in the last section by returning all values that were decodable to
+:class:`unicode` and omitting the filenames that were not.  This lead to the
+following output::
+
+    >>> import os
+    >>> import locale
+    >>> locale.getpreferredencoding()
+    'UTF-8'
+    >>> os.mkdir('/tmp/mine')
+    >>> os.chdir('/tmp/mine')
+    >>> open(b'nonsense_char_\xff', 'w').close()
+    >>> open('all_ascii', 'w').close()
+    >>> os.listdir('.')
+    ['all_ascii']
+
+The issue with this type of code is that it is silently doing something
+surprising.  The caller expects to get a full list of files back from
+:func:`os.listdir`.  Instead, it silently ignores some of the files, returning
+only a subset.  This leads to code that doesn't do what is expected that may
+go unnoticed until the code is in production and someone notices that
+something important is being missed.
+
+Raising a UnicodeException with no chance of recovery
+=====================================================
+
+Believe it or not, a few libraries exist that make it impossible to deal
+with unicode text without raising a :exc:`UnicodeError`.  What seems to occur
+in these libraries is that the library has functions that expect to receive
+a :class:`unicode` string.  However, internally, those functions call other
+functions that expect to receive a byte :class:`str`.  The programmer of the
+API was smart enough to convert from a :class:`unicode` string to a byte
+:class:`str` but they did not give the user the chance to specify the
+encodings to use or how to deal with errors.  This results in exceptions when
+the user passes in a byte :class:`str` because the initial function wants
+a :class:`unicode` string and exceptions when the user passes in
+a :class:`unicode` string because the function can't convert the string to
+bytes in the encoding that it's selected.
+
+Do not put the user in the position of not being able to use your API without
+raising a :exc:`UnicodeError` with certain values.  If you can only safely
+take :class:`unicode` strings, document that byte :class:`str` is not allowed
+and vice versa.  If you have to convert internally, make sure to give the
+caller of your function parameters to control the encoding and how to treat
+errors that may occur during the encoding/decoding process.  If your code will
+raise a :exc:`UnicodeError` with non-:term:`ASCII` values no matter what, you
+should probably rethink your API.
+
+-----------------
+Knowing your data
+-----------------
+
+If you've read all the way down to this section without skipping you've seen
+several admonitions about the type of data you are processing affecting the
+viability of the various API choices.
+
+Here's a few things to consider in your data:
+
+Do you need to operate on both bytes and unicode?
+=================================================
+
+Much of the data in libraries, programs, and the general environment outside
+of python is written where strings are sequences of bytes.  So when we
+interact with data that comes from outside of python or data that is about to
+leave python it may make sense to only operate on the data as a byte
+:class:`str`.  There's two times when this may make sense:
+
+1. The user is intended to hand the data to the function and then the function
+   takes care of sending the data outside of python (to the filesystem, over
+   the network, etc).
+2. The data is not representable as text.  For instance, writing a binary
+   file format.
+
+Even when your code is operating in this area you still need to think a little
+more about your data.  For instance, it might make sense for the person using
+your API to pass in :class:`unicode` strings and let the function convert that
+into the byte :class:`str` that it then sends over the wire.
+
+There are also times when it might make sense to operate only on
+:class:`unicode` strings.  :class:`unicode` represents text so anytime that
+you are working on textual data that isn't going to leave python it has the
+potential to be a :class:`unicode`-only API.  However, there's two things that
+you should consider when designing a :class:`unicode`-only API:
+
+1. As your API gains popularity, people are going to use your API in places
+   that you may not have thought of.  Corner cases in these other places may
+   mean that processing bytes is desirable.
+2. In python2, byte :class:`str` and :class:`unicode` are often used
+   interchangably with each other.  That means that people programming against
+   your API may have received :class:`str` from some other API and it would be
+   most convenient for their code if your API accepted it.
+
+.. note::
+
+    In python3, the separation between the text type and the byte type
+    are more clear.  So in python3, there's less need to have all APIs take
+    both unicode and bytes.
+
+Can you restrict the encodings?
+===============================
+If you determine that you have to deal with byte :class:`str` you should
+realize that not all encodings are created equal.  Each has different
+properties that may make it possible to provide a simpler API provided that
+you can reasonably tell the users of your API that they cannot use certain
+classes of encodings.
+
+As one example, if you are required to find a comma (``,``) in a byte
+:class:`str` you have different choices based on what encodings are allowed.
+If you can reasonably restrict your API users to only giving :term:`ASCII
+compatible` encodings you can do this simply by searching for the literal
+comma character because that character will be represented by the same byte
+sequence in all :term:`ASCII compatible` encodings.
+
+The following are some classes of encodings to be aware of as you decide how
+generic your code needs to be.
+
+Single byte encodings
+---------------------
+
+Single byte encodings can only represent 256 total characters.  They encode
+the :term:`code points` for a character to the equivalent number in a single
+byte.
+
+Most single byte encodings are :term:`ASCII compatible`.  :term:`ASCII
+compatible` encodings are the most likely to be usable without changes to code
+so this is good news.  A notable exception to this is the `EBDIC
+<http://en.wikipedia.org/wiki/Extended_Binary_Coded_Decimal_Interchange_Code>`_
+family of encodings.
+
+Multibyte encodings
+-------------------
+
+Multibyte encodings use more than one byte to encode some characters.
+
+Fixed width
+~~~~~~~~~~~
+
+Fixed width encodings have a set number of bytes to represent all of the
+characters in the character set.  ``UTF-32`` is an example of a fixed width
+encoding that uses four bytes per character and can express every unicode
+characters.  There are a number of problems with writing APIs that need to
+operate on fixed width, multibyte characters.  To go back to our earlier
+example of finding a comma in a string, we have to realize that even in
+``UTF-32`` where the :term:`code point` for :term:`ASCII` characters is the
+same as in :term:`ASCII`, the byte sequence for them is different.  So you
+cannot search for the literal byte character as it may pick up false
+positives and may break a byte sequence in an odd place.
+
+Variable Width
+~~~~~~~~~~~~~~
+
+ASCII compatible
+""""""""""""""""
+
+:term:`UTF-8` and the `EUC <http://en.wikipedia.org/wiki/Extended_Unix_Code>`_
+family of encodings are examples of :term:`ASCII compatible` multi-byte
+encodings.  They achieve this by adhering to two principles:
+
+* All of the :term:`ASCII` characters are represented by the byte that they
+  are in the :term:`ASCII` encoding.
+* None of the :term:`ASCII` byte sequences are reused in any other byte
+  sequence for a different character.
+
+Escaped
+"""""""
+
+Some multibyte encodings work by using only bytes from the :term:`ASCII`
+encoding but when a particular sequence of those byes is found, they are
+interpreted as meaning something other than their :term:`ASCII` values.
+``UTF-7`` is one such encoding that can encode all of the unicode
+:term:`code points`.  For instance, here's a some Japanese characters encoded as
+``UTF-7``::
+
+    >>> a = u'\u304f\u3089\u3068\u307f'
+    >>> print a
+    くらとみ
+    >>> print a.encode('utf-7')
+    +ME8wiTBoMH8-
+
+These encodings can be used when you need to encode unicode data that may
+contain non-:term:`ASCII` characters for inclusion in an :term:`ASCII` only
+transport medium or file.
+
+However, they are not :term:`ASCII compatible` in the sense that we used
+earlier as the bytes that represent a :term:`ASCII` character are being reused
+as part of other characters.  If you were to search for a literal plus sign in
+this encoded string, you would run across many false positives, for instance.
+
+Other
+"""""
+
+There are many other popular variable width encodings, for instance ``UTF-16``
+and ``shift-JIS``.  Many of these are not :term:`ASCII compatible` so you
+cannot search for a literal :term:`ASCII` character without danger of false
+positives or false negatives.

+Python 2.4 compatibility
+------------------------
+
+At the moment, we're supporting python-2.4 and above.  Understand that there's
+a lot of python features that we cannot use because of this.
+
+Sometimes modules in the |stdlib|_ can be added to kitchen so that they're
+available.  When we do that we need to be careful of several things:
+
+1. Keep the module in sync with the version in the python-2.x trunk.  Use
+   :file:`maintainers/sync-copied-files.py` for this.
+2. Sync the unittests as well as the module.
+3. Be aware that not all modules are written to remain compatible with
+   Python-2.4 and might use python language features that were not present
+   then (generator expressions, relative imports, decorators, with, try: with
+   both except: and finally:, etc)  These are not good candidates for
+   importing into kitchen as they require more work to keep synced.
+
+---------
+Unittests
+---------
+
+* At least smoketest your code (make sure a function will return expected
+  values for one set of inputs).
+* Note that even 100% coverage is not a guarantee of working code!  Good tests
+  will realize that you need to also give multiple inputs that test the code
+  paths of called functions that are outside of your code.  Example::
+
+        def to_unicode(msg, encoding='utf8', errors='replace'):
+            return unicode(msg, encoding, errors)
+
+        # Smoketest only.  This will give 100% coverage for your code (it
+        # tests all of the code inside of to_unicode) but it leaves a lot of
+        # room for errors as it doesn't test all combinations of arguments
+        # that are then passed to the unicode() function.
+
+        tools.ok_(to_unicode('abc') == u'abc')
+
+        # Better -- tests now cover non-ascii characters and that error conditions
+        # occur properly.  There's a lot of other permutations that can be
+        # added along these same lines.
+        tools.ok_(to_unicode(u'café', 'utf8', 'replace'))
+        tools.assert_raises(UnicodeError, to_unicode, [u'cafè ñunru'.encode('latin1')])
+
+* We're using nose for unittesting.  Rather than depend on unittest2
+  functionality, use the functions that nose provides.
+* Remember to maintain python-2.4 compatibility even in unittests.
+
+----------------------------
+Docstrings and documentation
+----------------------------
+
+We use sphinx to build our documentation.  We use the sphinx autodoc extension
+to pull docstrings out of the modules for API documentation.  This means that
+docstrings for subpackages and modules should follow a certain pattern.  The
+general structure is:
+
+* Introductory material about a module in the module's top level docstring.
+
+  * Introductory material should begin with a level two title: an overbar and
+    underbar of '-'.
+
+* docstrings for every function.
+
+  * The first line is a short summary of what the function does
+  * This is followed by a blank line
+  * The next lines are a `field list
+    <http://sphinx.pocoo.org/markup/desc.html#info-field-lists>_` giving
+    information about the function's signature.  We use the keywords:
+    ``arg``, ``kwarg``, ``raises``, ``returns``, and sometimes ``rtype``.  Use
+    these to describe all arguments, key word arguments, exceptions raised,
+    and return values using these.
+
+    * Parameters that are ``kwarg`` should specify what their default
+      behaviour is.

+  release of kitchen.  At that point, we're declaring that we have some
+  confidence that we won't need to break backwards compatibility for a while.
+* The Minor version increments for any backwards incompatible API changes.
+  When this is updated, we reset micro to zero.
+* The Micro version increments for any other changes (backwards compatible API
+  changes, pure bugfixes, etc).
+
+.. note::
+
+    Versioning is only updated for releases that generate sdists and new
+    uploads to the download directory.  Usually we update the version
+    information for the library just before release.  By contrast, we update
+    kitchen :ref:`subpackage-versioning` when an API change is made.  When in
+    doubt, look at the version information in the last release.
+
+----
+I18N
+----
+
+All strings that are used as feedback for users need to be translated.
+:mod:`kitchen` sets up several functions for this.  :func:`_` is used for
+marking things that are shown to users via print, GUIs, or other "standard"
+methods.  Strings for exceptions are marked with :func:`b_`.  This function
+returns a byte :class:`str` which is needed for use with exceptions::
+
+    from kitchen import _, b_
+
+    def print_message(msg, username):
+        print _('%(user)s, your message of the day is:  %(message)s') % {
+                'message': msg, 'user': username}
+
+        raise Exception b_('Test message')
+
+This serves several purposes:
+
+* It marks the strings to be extracted by an xgettext-like program.
+* :func:`_` is a function that will substitute available translations at
+  runtime.
+
+.. note::
+
+    By using the ``%()s with dict`` style of string formatting, we make this
+    string friendly to translators that may need to reorder the variables when
+    they're translating the string.
+
+`paver <http://www.blueskyonmars.com/projects/paver/>_` and `babel
+<http://babel.edgewall.org/>_` are used to extract the strings.
+
+-----------
+API updates
+-----------
+
+Kitchen strives to have a long deprecation cycle so that people have time to
+switch away from any APIs that we decide to discard.  Discarded APIs should
+raise a :exc:`DeprecationWarning` and clearly state in the warning message and
+the docstring how to convert old code to use the new interface.  An example of
+deprecating a function::
+
+    import warnings
+
+    from kitchen import _
+    from  kitchen.text.converters import to_bytes, to_unicode
+    from kitchen.text.new_module import new_function
+
+    def old_function(param):
+        '''**Deprecated**
+
+        This function is deprecated.  Use
+        :func:`kitchen.text.new_module.new_function` instead. If you want
+        unicode strngs as output, switch to::
+
+            >>> from kitchen.text.new_module import new_function
+            >>> output = new_function(param)
+
+        If you want byte strings, use::
+
+            >>> from kitchen.text.new_module import new_function
+            >>> from kitchen.text.converters import to_bytes
+            >>> output = to_bytes(new_function(param))
+        '''
+        warnings.warn(_('kitchen.text.old_function is deprecated.  Use'
+            ' kitchen.text.new_module.new_function instead'),
+            DeprecationWarning, stacklevel=2)
+
+        as_unicode = isinstance(param, unicode)
+        message = new_function(to_unicode(param))
+        if not as_unicode:
+            message = to_bytes(message)
+        return message
+
+If a particular API change is very intrusive, it may be better to create a new
+version of the subpackage and ship both the old version and the new version.
+
+---------
+NEWS file
+---------
+
+Update the :file:`NEWS` file when you make a change that will be visible to
+the users.  This is not a ChangeLog file so we don't need to list absolutely
+everything but it should give the user an idea of how this version differs
+from prior versions.  API changes should be listed here explicitly.  bugfixes
+can be more general::
+
+    -----
+    0.2.0
+    -----
+    * Relicense to LGPLv2+
+    * Add kitchen.text.format module with the following functions:
+      textual_width, textual_width_chop.
+    * Rename the kitchen.text.utils module to kitchen.text.misc.  use of the
+      old names is deprecated but still available.
+    * bugfixes applied to kitchen.pycompat24.defaultdict that fixes some
+      tracebacks
+
+-------------------
+Kitchen subpackages
+-------------------
+
+Kitchen itself is a namespace.  The kitchen sdist (tarball) provides certain
+useful subpackages.
+
+.. seealso::
+
+    `Kitchen addon packages`_
+        For information about subpackages not distributed in the kitchen sdist
+        that install into the kitchen namespace.
+
+.. _subpackage-versioning:
+
+Versioning
+==========
+
+Each subpackage should have its own version information which is independent
+of the other kitchen subpackages and the main kitchen library version. This is
+used so that code that depends on kitchen APIs can check the version
+information.  The standard way to do this is to put something like this in the
+subpackage's :file:`__init__.py`::
+
+    from kitchen.versioning import version_tuple_to_string
+
+    __version_info__ = ((1, 0, 0),)
+    __version__ = version_tuple_to_string(__version_info__)
+
+:attr:`__version_info__` is documented in :mod:`kitchen.versioning`.  The
+values of the first tuple should describe API changes to the module.  There
+are at least three numbers present in the tuple: (Major, minor, micro).  The
+major version number is for backwards incompatible changes (For
+instance, removing a function, or adding a new mandatory argument to
+a function).  Whenever one of these occurs, you should increment the major
+number and reset minor and micro to zero.  The second number is the minor
+version.  Anytime new but backwards compatible changes are introduced this
+number should be incremented and the micro version number reset to zero.  The
+micro version should be incremented when a change is made that does not change
+the API at all.  This is a common case for bugfixes, for instance.
+
+Version information beyond the first three parts of the first tuple may be
+useful for versioning but semantically have similar meaning to the micro
+version.
+
+.. note::
+
+    We update the :attr:`__version_info__` tuple when the API is updated.
+    This way there's less chance of forgetting to update the API version when
+    a new release is made.  However, we try to only increment the version
+    numbers a single step for any release.  So if kitchen-0.1.0 has
+    kitchen.text.__version__ == '1.0.1', kitchen-0.1.1 should have
+    kitchen.text.__version__ == '1.0.2' or '1.1.0' or '2.0.0'.
+
+Criteria for subpackages in kitchen
+===================================
+
+Supackages within kitchen should meet these criteria:
+
+* Generally useful or needed for other pieces of kitchen.
+
+* No mandatory requirements outside of the |stdlib|_.
+
+  * Optional requirements from outside the |stdlib|_ are allowed.  Things with
+    mandatory requirements are better placed in `kitchen addon packages`_
+
+* Somewhat API stable -- this is not a hard requirement.  We can change the
+  kitchen api.  However, it is better not to as people may come to depend on
+  it.
+
+  .. seealso::
+
+    `API Updates`_
+
+----------------------
+Kitchen addon packages
+----------------------
+
+Addon packages are very similar to subpackages integrated into the kitchen
+sdist.  This section just lists some of the differences to watch out for.
+
+setup.py
+========
+
+Your :file:`setup.py` should contain entries like this::
+
+    # It's suggested to use a dotted name like this so the package is easily
+    # findable on pypi:
+    setup(name='kitchen.config',
+        # Include kitchen in the keywords, again, for searching on pypi
+        keywords=['kitchen', 'configuration'],
+        # This package lives in the directory kitchen/config
+        packages=['kitchen.config'],
+        # [...]
+    )
+
+Package directory layout
+========================
+
+Create a :file:`kitchen` directory in the toplevel.  Place the addon
+subpackage in there.  For example::
+
+  ./                     <== toplevel with README, setup.py, NEWS, etc
+  kitchen/
+  kitchen/__init__.py
+  kitchen/config/        <== subpackage directory
+  kitchen/config/__init__.py
+
+Fake kitchen module
+===================
+
+The :file::`__init__.py` in the :file:`kitchen` directory is special.  It
+won't be installed.  It just needs to pull in the kitchen from the system so
+that you are able to test your module.  You should be able to use this
+boilerplate::
+
+    # Fake module.  This is not installed,  It's just made to import the real
+    # kitchen modules for testing this module
+    import pkgutil
+
+    # Extend the __path__ with everything in the real kitchen module
+    __path__ = pkgutil.extend_path(__path__, __name__)
+
+.. note::
+
+    :mod:`kitchen` needs to be findable by python for this to work.  Installed
+    in the :file:`site-packages` directory or adding it to the
+    :envvar:`PYTHONPATH` will work.
+
+Your unittests should now be able to find both your submodule and the main
+kitchen module.
+
+Versioning
+==========
+
+It is recommended that addon packages version similarly to
+:ref:`subpackage-versioning`.  The :data:`__version_info__` and
+:data:`__version__` strings can be changed independently of  the version
+exposed by setup.py so that you have both an API version
+(:data:`__version_info__`) and release version that's easier for people to
+parse.  However, you aren't required to do this and you could follow
+a different methodology if you want (for instance, :ref:`kitchen-versioning`)

+================================
+Kitchen, everything but the sink
+================================
+
+:Author: Toshio Kuratomi
+:Date: 19 March 2011
+:Version: 1.0.x
+
+We've all done it.  In the process of writing a brand new application we've
+discovered that we need a little bit of code that we've invented before.
+Perhaps it's something to handle unicode text.  Perhaps it's something to make
+a bit of python-2.5 code run on python-2.4.  Whatever it is, it ends up being
+a tiny bit of code that seems too small to worry about pushing into its own
+module so it sits there, a part of your current project, waiting to be cut and
+pasted into your next project.  And the next.  And the next.  And since that
+little bittybit of code proved so useful to you, it's highly likely that it
+proved useful to someone else as well.  Useful enough that they've written it
+and copy and pasted it over and over into each of their new projects.
+
+Well, no longer!  Kitchen aims to pull these small snippets of code into a few
+python modules which you can import and use within your project.  No more copy
+and paste!  Now you can let someone else maintain and release these small
+snippets so that you can get on with your life.
+
+This package forms the core of Kitchen.  It contains some useful modules for
+using newer |stdlib|_ modules on older python versions, text manipulation,
+:pep:`386` versioning, and initializing :mod:`gettext`.  With this package we're
+trying to provide a few useful features that don't have too many dependencies
+outside of the |stdlib|_.  We'll be releasing other modules that drop into the
+kitchen namespace to add other features (possibly with larger deps) as time
+goes on.
+
+------------
+Requirements
+------------
+
+We've tried to keep the core kitchen module's requirements lightweight.  At the
+moment kitchen only requires
+
+:python: 2.4 or later
+
+.. warning:: Kitchen-1.1.0 was the last release to support python-2.3.x.
+
+Soft Requirements
+=================
+
+If found, these libraries will be used to make the implementation of some part
+of kitchen better in some way.  If they are not present, the API that they
+enable will still exist but may function in a different manner.
+
+`chardet <http://pypi.python.org/pypi/chardet>`_
+    Used in :func:`~kitchen.text.misc.guess_encoding` and
+    :func:`~kitchen.text.converters.guess_encoding_to_xml` to help guess
+    encoding of byte strings being converted.  If not present, unknown
+    encodings will be converted as if they were ``latin1``
+
+---------------------------
+Other Recommended Libraries
+---------------------------
+
+These libraries implement commonly used functionality that everyone seems to
+invent.  Rather than reinvent their wheel, I simply list the things that they
+do well for now.  Perhaps if people can't find them normally, I'll add them as
+requirements in :file:`setup.py` or link them into kitchen's namespace.  For
+now, I just mention them here:
+
+`bunch <http://pypi.python.org/pypi/bunch/>`_
+    Bunch is a dictionary that you can use attribute lookup as well as bracket
+    notation to access.  Setting it apart from most homebrewed implementations
+    is the :func:`bunchify` function which will descend nested structures of
+    lists and dicts, transforming the dicts to Bunch's.
+`hashlib <http://code.krypto.org/python/hashlib/>`_
+    Python 2.5 and forward have a :mod:`hashlib` library that provides secure
+    hash functions to python.  If you're developing for python2.4 though, you
+    can install the standalone hashlib library and have access to the same
+    functions.
+`iterutils <http://pypi.python.org/pypi/iterutils/>`_
+    The python documentation for :mod:`itertools` has some examples
+    of other nice iterable functions that can be built from the
+    :mod:`itertools` functions.  This third-party module creates those recipes
+    as a module.
+`ordereddict <http://pypi.python.org/pypi/ordereddict/>`_
+    Python 2.7 and forward have a :mod:`~collections.OrderedDict` that
+    provides a :class:`dict` whose items are ordered (and indexable) as well
+    as named.
+`unittest2 <http://pypi.python.org/pypi/unittest2>`_
+    Python 2.7 has an updated :mod:`unittest` library with new functions not
+    present in the |stdlib|_ for Python 2.6 or less.  If you want to use those
+    new functions but need your testing framework to be compatible with older
+    Python the unittest2 library provides the update as an external module.
+`nose <http://somethingaboutorange.com/mrl/projects/nose/>`_
+    If you want to use a test discovery tool instead of the unittest
+    framework, nosetests provides a simple to use way to do that.

+1.0.0 Porting Guide
+===================
+
+The 0.1 through 1.0.0 releases focused on bringing in functions from yum and

+kitchen replacements.

+===================================  ===================
+
+.. [#f1] :func:`~kitchen.iterutils.isiterable` has changed slightly in
+    kitchen.  The :attr:`include_string` attribute has switched its default value
+    from :data:`True` to :data:`False`.  So you need to change code like::
+
+        >>> # Old code

+=================================  ===================
+
+.. [#y1] These yum methods provided fallback support for :mod:`gettext`
+    functions in case either ``gaftonmode`` was set or :mod:`gettext` failed
+    to return an object.  In kitchen, we can use the
+    :class:`kitchen.i18n.DummyTranslations` object to fulfill that role.
+    Please see :ref:`yum-i18n-init` for more suggestions on how to do this.
+
+.. [#y2] The yum version of these functions returned a byte :class:`str`.  The
+    kitchen version listed here returns a :class:`unicode` string.  If you
+    need a byte :class:`str` simply call
+    :func:`kitchen.text.converters.to_bytes` on the result.
+
+.. [#y3] The yum version of these functions would return either a byte
+    :class:`str` or a :class:`unicode` string depending on what the input
+    value was.  The kitchen version always returns :class:`unicode` strings.
+
+.. [#y4] :func:`yum.i18n.utf8_width_chop` performed two functions.  It
+    returned the piece of the message that fit in a specified width and the
+    width of that message.  In kitchen, you need to call two functions, one
+    for each action::
+
+        >>> # Old way
+        >>> utf8_width_chop(msg, 5)
+        (5, 'く ku')
+        >>> # New way
+        >>> from kitchen.text.display import textual_width, textual_width_chop
+        >>> (textual_width(msg), textual_width_chop(msg, 5))
+        (5, u'く ku')
+
+.. [#y5] If the yum version of :func:`~yum.i18n.to_unicode` or
+    :func:`~yum.i18n.to_utf8` is given an object that is not a string, it
+    returns the object itself.  :func:`kitchen.text.converters.to_unicode` and
+    :func:`kitchen.text.converters.to_bytes` default to returning the
+    ``simplerepr`` of the object instead.  If you want the yum behaviour, set
+    the :attr:`nonstring` parameter to ``passthru``::
+
+        >>> from kitchen.text.converters import to_unicode
+        >>> to_unicode(5)
+        u'5'
+        >>> to_unicode(5, nonstring='passthru')
+        5
+
+.. [#y6] :func:`yum.i18n.to_str` could return either a byte :class:`str`.  or
+    a :class:`unicode` string In kitchen you can get the same effect but you
+    get to choose whether you want a byte :class:`str` or a :class:`unicode`
+    string.  Use :func:`~kitchen.text.converters.to_bytes` for :class:`str`
+    and :func:`~kitchen.text.converters.to_unicode` for :class:`unicode`.
+
+.. [#y7] :func:`yum.misc.to_xml` was buggy as written.  I think the intention
+    was for you to be able to pass a byte :class:`str` or :class:`unicode`
+    string in and get out a byte :class:`str` that was valid to use in an xml
+    file.  The two kitchen functions
+    :func:`~kitchen.text.converters.byte_string_to_xml` and
+    :func:`~kitchen.text.converters.unicode_to_xml` do that for each string
+    type.
+
+.. [#y8] When porting :func:`yum.i18n.exception2msg` to use kitchen, you
+    should setup two wrapper functions to aid in your port.  They'll look like
+    this:
+
+    .. code-block:: python
+
+        from kitchen.text.converters import EXCEPTION_CONVERTERS, \
+            BYTE_EXCEPTION_CONVERTERS, exception_to_unicode, \
+            exception_to_bytes
+        def exception2umsg(e):
+            '''Return a unicode representation of an exception'''
+            c = [lambda e: e.value]
+            c.extend(EXCEPTION_CONVERTERS)
+            return exception_to_unicode(e, converters=c)
+        def exception2bmsg(e):
+            '''Return a utf8 encoded str representation of an exception'''
+            c = [lambda e: e.value]
+            c.extend(BYTE_EXCEPTION_CONVERTERS)
+            return exception_to_bytes(e, converters=c)
+
+    The reason to define this wrapper is that many of the exceptions in yum
+    put the message in the :attr:`value` attribute of the :exc:`Exception`
+    instead of adding it to the :attr:`args` attribute.  So the default
+    :data:`~kitchen.text.converters.EXCEPTION_CONVERTERS` don't know where to
+    find the message.  The wrapper tells kitchen to check the :attr:`value`
+    attribute for the message.  The reason to define two wrappers may be less
+    obvious.  :func:`yum.i18n.exception2msg` can return a :class:`unicode`
+    string or a byte :class:`str` depending on a combination of what
+    attributes are present on the :exc:`Exception` and what locale the
+    function is being run in.  By contrast,
+    :func:`kitchen.text.converters.exception_to_unicode` only returns
+    :class:`unicode` strings and
+    :func:`kitchen.text.converters.exception_to_bytes` only returns byte
+    :class:`str`.  This is much safer as it keeps code that can only handle
+    :class:`unicode` or only handle byte :class:`str` correctly from getting
+    the wrong type when an input changes but it means you need to examine the
+    calling code when porting from :func:`yum.i18n.exception2msg` and use the
+    appropriate wrapper.
+
+.. _yum-i18n-init:
+
+Initializing Yum i18n
+=====================
+
+Previously, yum had several pieces of code to initialize i18n.  From the
+toplevel of :file:`yum/i18n.py`::
+
+    try:.
+        '''
+        Setup the yum translation domain and make _() and P_() translation wrappers
+        available.
+        using ugettext to make sure translated strings are in Unicode.
+        '''
+        import gettext
+        t = gettext.translation('yum', fallback=True)
+        _ = t.ugettext
+        P_ = t.ungettext
+    except:
+        '''
+        Something went wrong so we make a dummy _() wrapper there is just
+        returning the same text
+        '''
+        _ = dummy_wrapper
+        P_ = dummyP_wrapper
+
+With kitchen, this can be changed to this::
+
+    from kitchen.i18n import easy_gettext_setup, DummyTranslations
+    try:
+        _, P_ = easy_gettext_setup('yum')
+    except:
+        translations = DummyTranslations()
+        _ = translations.ugettext
+        P_ = translations.ungettext
+
+.. note:: In :ref:`overcoming-frustration`, it is mentioned that for some
+    things (like exception messages), using the byte :class:`str` oriented
+    functions is more appropriate.  If this is desired, the setup portion is
+    only a second call to :func:`kitchen.i18n.easy_gettext_setup`::
+
+        b_, bP_ = easy_gettext_setup('yum', use_unicode=False)
+
+The second place where i18n is setup is in :meth:`yum.YumBase._getConfig` in
+:file:`yum/__init_.py` if ``gaftonmode`` is in effect::
+
+    if startupconf.gaftonmode:
+        global _
+        _ = yum.i18n.dummy_wrapper
+
+This can be changed to::
+
+    if startupconf.gaftonmode:
+        global _
+        _ = DummyTranslations().ugettext()

+
+==========================================================
+Overcoming frustration: Correctly using unicode in python2
+==========================================================
+
+In python-2.x, there's two types that deal with text.
+
+1. :class:`str` is for strings of bytes.  These are very similar in nature to
+   how strings are handled in C.
+2. :class:`unicode` is for strings of unicode :term:`code points`.
+
+.. note::
+
+    **Just what the dickens is "Unicode"?**
+
+    One mistake that people encountering this issue for the first time make is
+    confusing the :class:`unicode` type and the encodings of unicode stored in
+    the :class:`str` type.  In python, the :class:`unicode` type stores an
+    abstract sequence of :term:`code points`.  Each :term:`code point`
+    represents a :term:`grapheme`.  By contrast, byte :class:`str` stores
+    a sequence of bytes which can then be mapped to a sequence of :term:`code
+    points`.  Each unicode encoding (:term:`UTF-8`, UTF-7, UTF-16, UTF-32,
+    etc) maps different sequences of bytes to the unicode :term:`code points`.
+    
+    What does that mean to you as a programmer?  When you're dealing with text
+    manipulations (finding the number of characters in a string or cutting
+    a string on word boundaries) you should be dealing with :class:`unicode`
+    strings as they abstract characters in a manner that's appropriate for
+    thinking of them as a sequence of letters that you will see on a page.
+    When dealing with I/O, reading to and from the disk, printing to
+    a terminal, sending something over a network link, etc, you should be dealing
+    with byte :class:`str` as those devices are going to need to deal with
+    concrete implementations of what bytes represent your abstract characters.
+
+In the python2 world many APIs use these two classes interchangably but there
+are several important APIs where only one or the other will do the right
+thing.  When you give the wrong type of string to an API that wants the other
+type, you may end up with an exception being raised (:exc:`UnicodeDecodeError`
+or :exc:`UnicodeEncodeError`).  However, these exceptions aren't always raised
+because python implicitly converts between types... *sometimes*.
+
+-----------------------------------
+Frustration #1: Inconsistent Errors
+-----------------------------------
+
+Although converting when possible seems like the right thing to do, it's
+actually the first source of frustration.  A programmer can test out their
+program with a string like: ``The quick brown fox jumped over the lazy dog``
+and not encounter any issues.  But when they release their software into the
+wild, someone enters the string: ``I sat down for coffee at the café`` and
+suddenly an exception is thrown.  The reason?  The mechanism that converts
+between the two types is only able to deal with :term:`ASCII` characters.
+Once you throw non-:term:`ASCII` characters into your strings, you have to
+start dealing with the conversion manually.
+
+So, if I manually convert everything to either byte :class:`str` or
+:class:`unicode` strings, will I be okay?  The answer is.... *sometimes*.
+
+---------------------------------
+Frustration #2: Inconsistent APIs
+---------------------------------
+
+The problem you run into when converting everything to byte :class:`str` or
+:class:`unicode` strings is that you'll be using someone else's API quite
+often (this includes the APIs in the |stdlib|_) and find that the API will only
+accept byte :class:`str` or only accept :class:`unicode` strings.  Or worse,
+that the code will accept either when you're dealing with strings that consist
+solely of :term:`ASCII` but throw an error when you give it a string that's
+got non-:term:`ASCII` characters.  When you encounter these APIs you first
+need to identify which type will work better and then you have to convert your
+values to the correct type for that code.  Thus the programmer that wants to
+proactively fix all unicode errors in their code needs to do two things:
+
+1. You must keep track of what type your sequences of text are.  Does
+   ``my_sentence`` contain :class:`unicode` or :class:`str`?  If you don't
+   know that then you're going to be in for a world of hurt.
+2. Anytime you call a function you need to evaluate whether that function will
+   do the right thing with :class:`str` or :class:`unicode` values.  Sending
+   the wrong value here will lead to a :exc:`UnicodeError` being thrown when
+   the string contains non-:term:`ASCII` characters.
+
+.. note::
+
+    There is one mitigating factor here.  The python community has been
+    standardizing on using :class:`unicode` in all its APIs.  Although there
+    are some APIs that you need to send byte :class:`str` to in order to be
+    safe, (including things as ubiquitous as :func:`print` as we'll see in the
+    next section), it's getting easier and easier to use :class:`unicode`
+    strings with most APIs.
+
+------------------------------------------------
+Frustration #3: Inconsistent treatment of output
+------------------------------------------------
+
+Alright, since the python community is moving to using :class:`unicode`
+strings everywhere, we might as well convert everything to :class:`unicode`
+strings and use that by default, right?  Sounds good most of the time but
+there's at least one huge caveat to be aware of.  Anytime you output text to
+the terminal or to a file, the text has to be converted into a byte
+:class:`str`.  Python will try to implicitly convert from :class:`unicode` to
+byte :class:`str`... but it will throw an exception if the bytes are
+non-:term:`ASCII`::
+
+    >>> string = unicode(raw_input(), 'utf8')
+    café
+    >>> log = open('/var/tmp/debug.log', 'w')
+    >>> log.write(string)
+    Traceback (most recent call last):
+      File "<stdin>", line 1, in <module>
+    UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 3: ordinal not in range(128)
+
+Okay, this is simple enough to solve:  Just convert to a byte :class:`str` and
+we're all set::
+
+    >>> string = unicode(raw_input(), 'utf8')
+    café
+    >>> string_for_output = string.encode('utf8', 'replace')
+    >>> log = open('/var/tmp/debug.log', 'w')
+    >>> log.write(string_for_output)
+    >>>
+
+So that was simple, right?  Well... there's one gotcha that makes things a bit
+harder to debug sometimes.  When you attempt to write non-:term:`ASCII`
+:class:`unicode` strings to a file-like object you get a traceback everytime.
+But what happens when you use :func:`print`?  The terminal is a file-like object
+so it should raise an exception right?  The answer to that is....
+*sometimes*:
+
+.. code-block:: pycon
+
+    $ python
+    >>> print u'café'
+    café
+
+No exception.  Okay, we're fine then?
+
+We are until someone does one of the following:
+
+* Runs the script in a different locale:
+
+  .. code-block:: pycon
+
+    $ LC_ALL=C python
+    >>> # Note: if you're using a good terminal program when running in the C locale
+    >>> # The terminal program will prevent you from entering non-ASCII characters
+    >>> # python will still recognize them if you use the codepoint instead:
+    >>> print u'caf\xe9'
+    Traceback (most recent call last):
+      File "<stdin>", line 1, in <module>
+    UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 3: ordinal not in range(128)
+
+* Redirects output to a file:
+
+  .. code-block:: pycon
+
+    $ cat test.py
+    #!/usr/bin/python -tt
+    # -*- coding: utf-8 -*-
+    print u'café'
+    $ ./test.py  >t
+    Traceback (most recent call last):
+      File "./test.py", line 4, in <module>
+        print u'café'
+    UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 3: ordinal not in range(128)
+
+Okay, the locale thing is a pain but understandable: the C locale doesn't
+understand any characters outside of :term:`ASCII` so naturally attempting to
+display those won't work.  Now why does redirecting to a file cause problems?
+It's because :func:`print` in python2 is treated specially.  Whereas the other
+file-like objects in python always convert to :term:`ASCII` unless you set
+them up differently, using :func:`print` to output to the terminal will use
+the user's locale to convert before sending the output to the terminal.  When
+:func:`print` is not outputting to the terminal (being redirected to a file,
+for instance), :func:`print` decides that it doesn't know what locale to use
+for that file and so it tries to convert to :term:`ASCII` instead.
+
+So what does this mean for you, as a programmer?  Unless you have the luxury
+of controlling how your users use your code, you should always, always, always
+convert to a byte :class:`str` before outputting strings to the terminal or to
+a file.  Python even provides you with a facility to do just this.  If you
+know that every :class:`unicode` string you send to a particular file-like
+object (for instance, :data:`~sys.stdout`) should be converted to a particular
+encoding you can use a :class:`codecs.StreamWriter` object to convert from
+a :class:`unicode` string into a byte :class:`str`.  In particular,
+:func:`codecs.getwriter` will return a :class:`~codecs.StreamWriter` class
+that will help you to wrap a file-like object for output.  Using our
+:func:`print` example:
+
+.. code-block:: python
+
+    $ cat test.py
+    #!/usr/bin/python -tt
+    # -*- coding: utf-8 -*-
+    import codecs
+    import sys
+
+    UTF8Writer = codecs.getwriter('utf8')
+    sys.stdout = UTF8Writer(sys.stdout)
+    print u'café'
+    $ ./test.py  >t
+    $ cat t
+    café
+
+-----------------------------------------
+Frustrations #4 and #5 -- The other shoes
+-----------------------------------------
+
+In English, there's a saying "waiting for the other shoe to drop".  It means
+that when one event (usually bad) happens, you come to expect another event
+(usually worse) to come after.  In this case we have two other shoes.
+
+
+Frustration #4: Now it doesn't take byte strings?!
+==================================================
+
+If you wrap :data:`sys.stdout` using :func:`codecs.getwriter` and think you
+are now safe to print any variable without checking its type I am afraid
+I must inform you that you're not paying enough attention to :term:`Murphy's
+Law`.  The :class:`~codecs.StreamWriter` that :func:`codecs.getwriter`
+provides will take :class:`unicode` strings and transform them into byte
+:class:`str` before they get to :data:`sys.stdout`.  The problem is if you
+give it something that's already a byte :class:`str` it tries to transform
+that as well.  To do that it tries to turn the byte :class:`str` you give it
+into :class:`unicode` and then transform that back into a byte :class:`str`...
+and since it uses the :term:`ASCII` codec to perform those conversions,
+chances are that it'll blow up when making them::
+
+    >>> import codecs
+    >>> import sys
+    >>> UTF8Writer = codecs.getwriter('utf8')
+    >>> sys.stdout = UTF8Writer(sys.stdout)
+    >>> print 'café'
+    Traceback (most recent call last):
+      File "<stdin>", line 1, in <module>
+      File "/usr/lib64/python2.6/codecs.py", line 351, in write
+        data, consumed = self.encode(object, self.errors)
+    UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 3: ordinal not in range(128)
+
+To work around this, kitchen provides an alternate version of
+:func:`codecs.getwriter` that can deal with both byte :class:`str` and
+:class:`unicode` strings.  Use :func:`kitchen.text.converters.getwriter` in
+place of the :mod:`codecs` version like this::
+
+    >>> import sys
+    >>> from kitchen.text.converters import getwriter
+    >>> UTF8Writer = getwriter('utf8')
+    >>> sys.stdout = UTF8Writer(sys.stdout)
+    >>> print u'café'
+    café
+    >>> print 'café'
+    café
+
+-------------------------------------------
+Frustration #5: Inconsistent APIs Part deux
+-------------------------------------------
+Sometimes you do everything right in your code but other people's code fails
+you.  With unicode issues this happens more often than we want.  A glaring
+example of this is when you get values back from a function that aren't
+consistently :class:`unicode` string or byte :class:`str`.
+
+An example from the |stdlib|_ is :mod:`gettext`.  The :mod:`gettext` functions
+are used to help translate messages that you display to users in the users'
+native languages.  Since most languages contain letters outside of the
+:term:`ASCII` range, the values that are returned contain unicode characters.
+:mod:`gettext` provides you with :meth:`~gettext.GNUTranslations.ugettext` and
+:meth:`~gettext.GNUTranslations.ungettext` to return these translations as
+:class:`unicode` strings and :meth:`~gettext.GNUTranslations.gettext`,
+:meth:`~gettext.GNUTranslations.ngettext`,
+:meth:`~gettext.GNUTranslations.lgettext`, and
+:meth:`~gettext.GNUTranslations.lngettext` to return them as encoded byte
+:class:`str`.  Unfortunately, even though they're documented to return only
+one type of string or the other, the implementation has corner cases where the
+wrong type can be returned.
+
+This means that even if you separate your :class:`unicode` string and byte
+:class:`str` correctly before you pass your strings to a :mod:`gettext`
+function, afterwards, you might have to check that you have the right sort of
+string type again.
+
+.. note::
+
+    :mod:`kitchen.i18n` provides alternate gettext translation objects that
+    return only byte :class:`str` or only :class:`unicode` string.
+
+---------------
+A few solutions
+---------------
+
+Now that we've identified the issues, can we define a comprehensive strategy
+for dealing with them?
+
+Convert text at the border
+==========================
+
+If you get some piece of text from a library, read from a file, etc, turn it
+into a :class:`unicode` string immediately.  Since python is moving in the
+direction of :class:`unicode` strings everywhere it's going to be easier to
+work with :class:`unicode` strings within your code.
+
+If your code is heavily involved with using things that are bytes, you can do
+the opposite and convert all text into byte :class:`str` at the border and
+only convert to :class:`unicode` when you need it for passing to another
+library or performing string operations on it.
+
+In either case, the important thing is to pick a default type for strings and
+stick with it throughout your code.  When you mix the types it becomes much
+easier to operate on a string with a function that can only use the other type
+by mistake.
+
+.. note:: In python3, the abstract unicode type becomes much more prominent.
+    The type named ``str`` is the equivalent of python2's :class:`unicode` and
+    python3's ``bytes`` type replaces python2's :class:`str`.  Most APIs deal
+    in the unicode type of string with just some pieces that are low level
+    dealing with bytes.  The implicit conversions between bytes and unicode
+    is removed and whenever you want to make the conversion you need to do so
+    explicitly.
+
+When the data needs to be treated as bytes (or unicode) use a naming convention
+===============================================================================
+
+Sometimes you're converting nearly all of your data to :class:`unicode`
+strings but you have one or two values where you have to keep byte
+:class:`str` around.  This is often the case when you need to use the value
+verbatim with some external resource.  For instance, filenames or key values
+in a database.  When you do this, use a naming convention for the data you're
+working with so you (and others reading your code later) don't get confused
+about what's being stored in the value.
+
+If you need both a textual string to present to the user and a byte value for
+an exact match, consider keeping both versions around.  You can either use two
+variables for this or a :class:`dict` whose key is the byte value.
+
+.. note:: You can use the naming convention used in kitchen as a guide for
+    implementing your own naming convention.  It prefixes byte :class:`str`
+    variables of unknown encoding with ``b_`` and byte :class:`str` of known
+    encoding with the encoding name like: ``utf8_``.  If the default was to
+    handle :class:`str` and only keep a few :class:`unicode` values, those
+    variables would be prefixed with ``u_``.
+
+When outputting data, convert back into bytes
+=============================================
+
+When you go to send your data back outside of your program (to the filesystem,
+over the network, displaying to the user, etc) turn the data back into a byte
+:class:`str`.  How you do this will depend on the expected output format of
+the data.  For displaying to the user, you can use the user's default encoding
+using :func:`locale.getpreferredencoding`.  For entering into a file, you're best
+bet is to pick a single encoding and stick with it.
+
+.. warning::
+
+    When using the encoding that the user has set (for instance, using
+    :func:`locale.getpreferredencoding`, remember that they may have their
+    encoding set to something that can't display every single unicode
+    character.  That means when you convert from :class:`unicode` to a byte
+    :class:`str` you need to decide what should happen if the byte value is
+    not valid in the user's encoding.  For purposes of displaying messages to
+    the user, it's usually okay to use the ``replace`` encoding error handler
+    to replace the invalid characters with a question mark or other symbol
+    meaning the character couldn't be displayed.
+
+You can use :func:`kitchen.text.converters.getwriter` to do this automatically
+for :data:`sys.stdout`.  When creating exception messages be sure to convert
+to bytes manually.
+
+When writing unittests, include non-ASCII values and both unicode and str type
+==============================================================================
+
+Unless you know that a specific portion of your code will only deal with
+:term:`ASCII`, be sure to include non-:term:`ASCII` values in your unittests.
+Including a few characters from several different scripts is highly advised as
+well because some code may have special cased accented roman characters but
+not know how to handle characters used in Asian alphabets.
+
+Similarly, unless you know that that portion of your code will only be given
+:class:`unicode` strings or only byte :class:`str` be sure to try variables
+of both types in your unittests.  When doing this, make sure that the
+variables are also non-:term:`ASCII` as python's implicit conversion will mask
+problems with pure :term:`ASCII` data.  In many cases, it makes sense to check
+what happens if byte :class:`str` and :class:`unicode` strings that won't
+decode in the present locale are given.
+
+Be vigilant about spotting poor APIs
+====================================
+
+Make sure that the libraries you use return only :class:`unicode` strings or
+byte :class:`str`.  Unittests can help you spot issues here by running many
+variations of data through your functions and checking that you're still
+getting the types of string that you expect.
+
+Example: Putting this all together with kitchen
+===============================================
+
+The kitchen library provides a wide array of functions to help you deal with
+byte :class:`str` and :class:`unicode` strings in your program.  Here's
+a short example that uses many kitchen functions to do its work::
+
+    #!/usr/bin/python -tt
+    # -*- coding: utf-8 -*-
+    import locale
+    import os
+    import sys
+    import unicodedata
+
+    from kitchen.text.converters import getwriter, to_bytes, to_unicode
+    from kitchen.i18n import get_translation_object
+
+    if __name__ == '__main__':
+        # Setup gettext driven translations but use the kitchen functions so
+        # we don't have the mismatched bytes-unicode issues.
+        translations = get_translation_object('example')
+        # We use _() for marking strings that we operate on as unicode
+        # This is pretty much everything
+        _ = translations.ugettext
+        # And b_() for marking strings that we operate on as bytes.
+        # This is limited to exceptions
+        b_ = translations.lgettext
+
+        # Setup stdout
+        encoding = locale.getpreferredencoding()
+        Writer = getwriter(encoding)
+        sys.stdout = Writer(sys.stdout)
+
+        # Load data.  Format is filename\0description
+        # description should be utf-8 but filename can be any legal filename
+        # on the filesystem
+        # Sample datafile.txt:
+        #   /etc/shells\x00Shells available on caf\xc3\xa9.lan
+        #   /var/tmp/file\xff\x00File with non-utf8 data in the filename
+        #
+        # And to create /var/tmp/file\xff (under bash or zsh) do:
+        #   echo 'Some data' > /var/tmp/file$'\377'
+        datafile = open('datafile.txt', 'r')
+        data = {}
+        for line in datafile:
+            # We're going to keep filename as bytes because we will need the
+            # exact bytes to access files on a POSIX operating system.
+            # description, we'll immediately transform into unicode type.
+            b_filename, description = line.split('\0', 1)
+
+            # to_unicode defaults to decoding output from utf-8 and replacing
+            # any problematic bytes with the unicode replacement character
+            # We accept mangling of the description here knowing that our file
+            # format is supposed to use utf-8 in that field and that the
+            # description will only be displayed to the user, not used as
