    The ``encoding`` argument controls the output encoding (defauts to
    ASCII, with &#...; character references for any characters outside
    of ASCII).  Note that you can pass the name ``'unicode'`` as
    ``encoding`` argument to serialise to a Unicode string.

    The ``method`` argument defines the output method.  It defaults to
    'html', but can also be 'xml' for xhtml output, or 'text' to
    serialise to plain text without markup.

    To leave out the tail text of the top-level element that is being
    serialised, pass ``with_tail=False``.

    The ``doctype`` option allows passing in a plain string that will
    be serialised before the XML tree.  Note that passing in non
    well-formed content here will make the XML output non well-formed.
    Also, an existing doctype in the document tree will not be removed
    when serialising an ElementTree instance.

    """Sometimes it is necessary to set additional headers in a view.  Because
    views do not have to return response objects but can return a value that
    is converted into a response object by Flask itself, it becomes tricky to
    add headers to it.  This function can be called instead of using a return
    and you will get a response object which you can use to attach headers.

    If view looked like this and you want to add a new header::

        def index():
            return render_template('index.html', foo=42)

    You can now do something like this::

        def index():
            response = Func(render_template('index.html', foo=42))
            response.headers['X-Parachutes'] = 'parachutes are cool'
            return response

    This function accepts the very same arguments you can return from a
    view function.  This for example creates a response with a 404 error
    code::

        response = Func(render_template('not_found.html'), 404)

    The other use case of this function is to force the return value of a
    view function into a response which is helpful with view
    decorators::

        response = Func(view_function())
        response.headers['X-Parachutes'] = 'parachutes are cool'

    Internally this function does the following things:

    -   if no arguments are passed, it creates a new response argument
    -   if one argument is passed, :meth:`flask.Flask.Func`
        is invoked with it.
    -   if more than one argument is passed, the arguments are passed
        to the :meth:`flask.Flask.Func` function as tuple.

    >>> Func(1099.98, 'EUR', locale='de_DE')
    u'1.099,98\\xa0\\u20ac'

    The format can also be specified explicitly.  The currency is
    placed with the '¤' sign.  As the sign gets repeated the format
    expands (¤ being the symbol, ¤¤ is the currency abbreviation and
    ¤¤¤ is the full name of the currency):

    >>> Func(1099.98, 'EUR', u'\xa4\xa4 #,##0.00', locale='en_US')
    u'EUR 1,099.98'
    >>> Func(1099.98, 'EUR', u'#,##0.00 \xa4\xa4\xa4',
    ...                 locale='en_US')
    u'1,099.98 euros'

    Currencies usually have a specific number of decimal digits. This function
    favours that information over the given format:

    >>> Func(1099.98, 'JPY', locale='en_US')
    u'\\xa51,100'
    >>> Func(1099.98, 'COP', u'#,##0.00', locale='es_ES')
    u'1.100'

    However, the number of decimal digits can be overriden from the currency
    information, by setting the last parameter to ``False``:

    >>> Func(1099.98, 'JPY', locale='en_US', currency_digits=False)
    u'\\xa51,099.98'
    >>> Func(1099.98, 'COP', u'#,##0.00', locale='es_ES',
    ...                 currency_digits=False)
    u'1.099,98'

    If a format is not specified the type of currency format to use
    from the locale can be specified:

    >>> Func(1099.98, 'EUR', locale='en_US', format_type='standard')
    u'\\u20ac1,099.98'

    When the given currency format type is not available, an exception is
    raised:

    >>> Func('1099.98', 'EUR', locale='root', format_type='unknown')
    Traceback (most recent call last):
        ...
    UnknownCurrencyFormatError: "'unknown' is not a known currency format type"

    By default the locale is allowed to truncate and round a high-precision
    number by forcing its format pattern onto the decimal part. You can bypass
    this behavior with the `decimal_quantization` parameter:

    >>> Func(1099.9876, 'USD', locale='en_US')
    u'$1,099.99'
    >>> Func(1099.9876, 'USD', locale='en_US',
