:param string: An Unicode string.
:returns: A new Unicode string.
This is used for `ASCII case-insensitive
<http://encoding.spec.whatwg.org/#ascii-case-insensitive>`_
matching of encoding labels.
The same matching is also used, among other things,
for `CSS keywords <http://dev.w3.org/csswg/css-values/#keywords>`_.
This is different from the :meth:`~py:str.lower` method of Unicode strings
which also affect non-ASCII characters,
sometimes mapping them into the ASCII range:
>>> keyword = u'Bac\N{KELVIN SIGN}ground'
>>> assert keyword.lower() == u'background'
>>> assert ascii_lower(keyword) != keyword.lower()
>>> assert ascii_lower(keyword) == u'bac\N{KELVIN SIGN}ground'

Look for an encoding by its label.
This is the spec’s `get an encoding
<http://encoding.spec.whatwg.org/#concept-encoding-get>`_ algorithm.
Supported labels are listed there.
:param label: A string.
:returns:
An :class:`Encoding` object, or :obj:`None` for an unknown label.

"Pull"-based decoder.
:param input:
An iterable of byte strings.
The input is first consumed just enough to determine the encoding
based on the precense of a BOM,
then consumed on demand when the return value is.

An :class:`Encoding` object or a label string.
The encoding to use if :obj:`input` does note have a BOM.
:param errors: Type of error handling. See :func:`codecs.register`.
:raises: :exc:`~exceptions.LookupError` for an unknown encoding label.
:returns:
An ``(output, encoding)`` tuple.
:obj:`output` is an iterable of Unicode strings,
:obj:`encoding` is the :obj:`Encoding` that is being used.
