    :arg obj: Object to convert to a :class:`unicode` string.  This should
        normally be a byte :class:`str`
    :kwarg encoding: What encoding to try converting the byte :class:`str` as.
        Defaults to :term:`utf-8`
    :kwarg errors: If errors are found while decoding, perform this action.
        Defaults to ``replace`` which replaces the invalid bytes with
        a character that means the bytes were unable to be decoded.  Other
        values are the same as the error handling schemes in the `codec base
        classes
        <http://docs.python.org/library/codecs.html#codec-base-classes>`_.
        For instance ``strict`` which raises an exception and ``ignore`` which
        simply omits the non-decodable characters.
    :kwarg nonstring: How to treat nonstring values.  Possible values are:

        :simplerepr: Attempt to call the object's "simple representation"
            method and return that value.  Python-2.3+ has two methods that
            try to return a simple representation: :meth:`object.__unicode__`
            and :meth:`object.__str__`.  We first try to get a usable value
            from :meth:`object.__unicode__`.  If that fails we try the same
            with :meth:`object.__str__`.
        :empty: Return an empty :class:`unicode` string
        :strict: Raise a :exc:`TypeError`
        :passthru: Return the object unchanged
        :repr: Attempt to return a :class:`unicode` string of the repr of the
            object

        Default is ``simplerepr``

    :kwarg non_string: *Deprecated* Use :attr:`nonstring` instead
    :raises TypeError: if :attr:`nonstring` is ``strict`` and
        a non-:class:`basestring` object is passed in or if :attr:`nonstring`
        is set to an unknown value
    :raises UnicodeDecodeError: if :attr:`errors` is ``strict`` and
        :attr:`obj` is not decodable using the given encoding
    :returns: :class:`unicode` string or the original object depending on the
        value of :attr:`nonstring`.

    Usually this should be used on a byte :class:`str` but it can take both
    byte :class:`str` and :class:`unicode` strings intelligently.  Nonstring
    objects are handled in different ways depending on the setting of the
    :attr:`nonstring` parameter.

    The default values of this function are set so as to always return
    a :class:`unicode` string and never raise an error when converting from
    a byte :class:`str` to a :class:`unicode` string.  However, when you do
    not pass validly encoded text (or a nonstring object), you may end up with
    output that you don't expect.  Be sure you understand the requirements of
    your data, not just ignore errors by passing it through this function.

��Convert an object into a byte :class:`str`

    :arg obj: Object to convert to a byte :class:`str`.  This should normally
        be a :class:`unicode` string.
    :kwarg encoding: Encoding to use to convert the :class:`unicode` string
        into a byte :class:`str`.  Defaults to :term:`utf-8`.
    :kwarg errors: If errors are found while encoding, perform this action.
        Defaults to ``replace`` which replaces the invalid bytes with
        a character that means the bytes were unable to be encoded.  Other
        values are the same as the error handling schemes in the `codec base
        classes
        <http://docs.python.org/library/codecs.html#codec-base-classes>`_.
        For instance ``strict`` which raises an exception and ``ignore`` which
        simply omits the non-encodable characters.
    :kwarg nonstring: How to treat nonstring values.  Possible values are:

        :simplerepr: Attempt to call the object's "simple representation"
            method and return that value.  Python-2.3+ has two methods that
            try to return a simple representation: :meth:`object.__unicode__`
            and :meth:`object.__str__`.  We first try to get a usable value
            from :meth:`object.__str__`.  If that fails we try the same
            with :meth:`object.__unicode__`.
        :empty: Return an empty byte :class:`str`
        :strict: Raise a :exc:`TypeError`
        :passthru: Return the object unchanged
        :repr: Attempt to return a byte :class:`str` of the :func:`repr` of the
            object

        Default is ``simplerepr``.

    :kwarg non_string: *Deprecated* Use :attr:`nonstring` instead.
    :raises TypeError: if :attr:`nonstring` is ``strict`` and
        a non-:class:`basestring` object is passed in or if :attr:`nonstring`
        is set to an unknown value.
    :raises UnicodeEncodeError: if :attr:`errors` is ``strict`` and all of the
        bytes of :attr:`obj` are unable to be encoded using :attr:`encoding`.
    :returns: byte :class:`str` or the original object depending on the value
        of :attr:`nonstring`.

    .. warning::

        If you pass a byte :class:`str` into this function the byte
        :class:`str` is returned unmodified.  It is **not** re-encoded with
        the specified :attr:`encoding`.  The easiest way to achieve that is::

            to_bytes(to_unicode(text), encoding='utf-8')

        The initial :func:`to_unicode` call will ensure text is
        a :class:`unicode` string.  Then, :func:`to_bytes` will turn that into
        a byte :class:`str` with the specified encoding.

    Usually, this should be used on a :class:`unicode` string but it can take
    either a byte :class:`str` or a :class:`unicode` string intelligently.
    Nonstring objects are handled in different ways depending on the setting
    of the :attr:`nonstring` parameter.

    The default values of this function are set so as to always return a byte
    :class:`str` and never raise an error when converting from unicode to
    bytes.  However, when you do not pass an encoding that can validly encode
    the object (or a non-string object), you may end up with output that you
    don't expect.  Be sure you understand the requirements of your data, not
    just ignore errors by passing it through this function.

    :arg encoding: Encoding to use for transforming :class:`unicode` strings
        into byte :class:`str`.
    :rtype: :class:`codecs.StreamWriter`
    :returns: :class:`~codecs.StreamWriter` that you can instantiate to wrap output
        streams to automatically translate :class:`unicode` strings into :attr:`encoding`.

    This is a reimplemetation of :func:`codecs.getwriter` that returns
    a :class:`~codecs.StreamWriter` that resists issuing tracebacks.  The
    :class:`~codecs.StreamWriter` that is returned uses
    :func:`kitchen.text.converters.to_bytes` to convert :class:`unicode`
    strings into byte :class:`str`.  The departures from
    :func:`codecs.getwriter` are:

    1) The :class:`~codecs.StreamWriter` that is returned will take byte
       :class:`str` as well as :class:`unicode` strings.  Any byte
       :class:`str` will be passed through unmodified.
    2) The default error handler for unknown bytes is to ``replace`` the bytes
       with the unknown character (``?`` in most ascii-based encodings, ``�``
       in the utf encodings) whereas :func:`codecs.getwriter` defaults to
       ``strict``.  Like :class:`codecs.StreamWriter`, the returned
       :class:`~codecs.StreamWriter` can have its error handler changed in
       code by setting ``stream.errors = 'new_handler_name'``

    Example usage::

        $ LC_ALL=C python
        >>> import sys
        >>> from kitchen.text.converters import getwriter
        >>> UTF8Writer = getwriter('utf-8')
        >>> unwrapped_stdout = sys.stdout
        >>> sys.stdout = UTF8Writer(unwrapped_stdout)
        >>> print 'caf\xc3\xa9'
        café
        >>> print u'caf\xe9'
        café
        >>> ASCIIWriter = getwriter('ascii')
        >>> sys.stdout = ASCIIWriter(unwrapped_stdout)
        >>> print 'caf\xc3\xa9'
        café
        >>> print u'caf\xe9'
        caf?

    suitable for xml

    :arg string: :class:`unicode` string to encode into an XML compatible byte
        :class:`str`
    :kwarg encoding: encoding to use for the returned byte :class:`str`.
        Default is to encode to :term:`UTF-8`.  If some of the characters in
        :attr:`string` are not encodable in this encoding, the unknown
        characters will be entered into the output string using xml character
        references.
    :kwarg attrib: If :data:`True`, quote the string for use in an xml
        attribute.  If :data:`False` (default), quote for use in an xml text
        field.
    :kwarg control_chars: :term:`control characters` are not allowed in XML
        documents.  When we encounter those we need to know what to do.  Valid
        options are:

        :replace: (default) Replace the control characters with ``?``
        :ignore: Remove the characters altogether from the output
        :strict: Raise an :exc:`~kitchen.text.exceptions.XmlEncodeError`  when
            we encounter a :term:`control character`

    :raises kitchen.text.exceptions.XmlEncodeError: If :attr:`control_chars`
        is set to ``strict`` and the string to be made suitable for output to
        xml contains :term:`control characters` or if :attr:`string` is not
        a :class:`unicode` string then we raise this exception.
    :raises ValueError: If :attr:`control_chars` is set to something other than
        ``replace``, ``ignore``, or ``strict``.
    :rtype: byte :class:`str`
    :returns: representation of the :class:`unicode` string as a valid XML
        byte :class:`str`

    XML files consist mainly of text encoded using a particular charset.  XML
    also denies the use of certain bytes in the encoded text (example: ``ASCII
    Null``).  There are also special characters that must be escaped if they
    are present in the input (example: ``<``).  This function takes care of
    all of those issues for you.

    There are a few different ways to use this function depending on your
    needs.  The simplest invocation is like this::

       unicode_to_xml(u'String with non-ASCII characters: <"á と">')

    This will return the following to you, encoded in :term:`utf-8`::

      'String with non-ASCII characters: &lt;"á と"&gt;'

    Pretty straightforward.  Now, what if you need to encode your document in
    something other than :term:`utf-8`?  For instance, ``latin-1``?  Let's
    see::

       unicode_to_xml(u'String with non-ASCII characters: <"á と">', encoding='latin-1')
       'String with non-ASCII characters: &lt;"á &#12392;"&gt;'

    Because the ``と`` character is not available in the ``latin-1`` charset,
    it is replaced with ``&#12392;`` in our output.  This is an xml character
    reference which represents the character at unicode codepoint ``12392``, the
    ``と`` character.

    When you want to reverse this, use :func:`xml_to_unicode` which will turn
    a byte :class:`str` into a :class:`unicode` string and replace the xml
    character references with the unicode characters.

    XML also has the quirk of not allowing :term:`control characters` in its
    output.  The :attr:`control_chars` parameter allows us to specify what to
    do with those.  For use cases that don't need absolute character by
    character fidelity (example: holding strings that will just be used for
    display in a GUI app later), the default value of ``replace`` works well::

        unicode_to_xml(u'String with disallowed control chars: \u0000\u0007')
        'String with disallowed control chars: ??'

    If you do need to be able to reproduce all of the characters at a later
    date (examples: if the string is a key value in a database or a path on a
    filesystem) you have many choices.  Here are a few that rely on ``utf-7``,
    a verbose encoding that encodes :term:`control characters` (as well as
    non-:term:`ASCII` unicode values) to characters from within the
    :term:`ASCII` printable characters.  The good thing about doing this is
    that the code is pretty simple.  You just need to use ``utf-7`` both when
    encoding the field for xml and when decoding it for use in your python
    program::

        unicode_to_xml(u'String with unicode: と and control char: \u0007', encoding='utf7')
        'String with unicode: +MGg and control char: +AAc-'
        # [...]
        xml_to_unicode('String with unicode: +MGg and control char: +AAc-', encoding='utf7')
        u'String with unicode: と and control char: \u0007'

    As you can see, the ``utf-7`` encoding will transform even characters that
    would be representable in :term:`utf-8`.  This can be a drawback if you
    want unicode characters in the file to be readable without being decoded
    first.  You can work around this with increased complexity in your
    application code::

        encoding = 'utf-8'
        u_string = u'String with unicode: と and control char: \u0007'
        try:
            # First attempt to encode to utf8
            data = unicode_to_xml(u_string, encoding=encoding, errors='strict')
        except XmlEncodeError:
            # Fallback to utf-7
            encoding = 'utf-7'
            data = unicode_to_xml(u_string, encoding=encoding, errors='strict')
        write_tag('<mytag encoding=%s>%s</mytag>' % (encoding, data))
        # [...]
        encoding = tag.attributes.encoding
        u_string = xml_to_unicode(u_string, encoding=encoding)

    Using code similar to that, you can have some fields encoded using your
    default encoding and fallback to ``utf-7`` if there are :term:`control
    characters` present.

    .. note::

        If your goal is to preserve the :term:`control characters` you cannot
        save the entire file as ``utf-7`` and set the xml encoding parameter
        to ``utf-7`` if your goal is to preserve the :term:`control
        characters`.  Because XML doesn't allow :term:`control characters`,
        you have to encode those separate from any encoding work that the XML
        parser itself knows about.

    :kwarg control_chars: XML does not allow :term:`control characters`.  When
        we encounter those we need to know what to do.  Valid options are:

    Use this when you have a byte :class:`str` representing text that you need
    to make suitable for output to xml.  There are several cases where this
    is the case.  For instance, if you need to transform some strings encoded
    in ``latin-1`` to :term:`utf-8` for output::

        utf8_string = byte_string_to_xml(latin1_string, input_encoding='latin-1')

    If you already have strings in the proper encoding you may still want to
    use this function to remove :term:`control characters`::

        cleaned_string = byte_string_to_xml(string, input_encoding='utf-8', output_encoding='utf-8')
