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' �utf8)�encode�lower�decode)�strings ��/builddir/build/BUILDROOT/alt-python312-pip-23.3.1-1.el8.x86_64/opt/alt/python312/lib/python3.12/site-packages/pip/_vendor/webencodings/__init__.py� ascii_lowerr # s' � �. �=�=�� � &� &� (� /� /�� 7�7� c �0 � t | j d� � } t j | � }|�yt j |� }|�L|dk( rddlm} n+t j ||� }t j |� }t ||� }|t |< |S )u< Look for an encoding by its label.
