    This is a Python implementation of the `WHATWG Encoding standard
    <http://encoding.spec.whatwg.org/>`. See README for details.

    :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.
