This is based on the presence of a BOM (Byte Order Mark), an @charset rule, and encoding meta-information.

  • css_bytes: A byte string.
  • protocol_encoding: The encoding label, if any, defined by HTTP or equivalent protocol. (e.g. via the charset parameter of the Content-Type header.)
  • environment_encoding: An optional Encoding object for the environment encoding, if any.

Returns the encoding to use.
