Determine the character encoding from the passed metadata and the
``@charset`` rule in the stylesheet (if any); and decode accordingly.
If no encoding information is available or decoding fails,
decoding defaults to UTF-8 and then fall back on ISO-8859-1.
:param css_bytes:
a CSS stylesheet as a byte string
:param protocol_encoding:
The "charset" parameter of a "Content-Type" HTTP header (if any),
