        The detect_encoding() function is used to detect the encoding that should
        be used to decode a Python source file.  It requires one argument, readline,
        in the same way as the tokenize() generator.

        It will call readline a maximum of twice, and return the encoding used
        (as a string) and a list of any lines (left as bytes) it has read in.

        It detects the encoding from the presence of a utf-8 bom or an encoding
        cookie as specified in pep-0263.  If both a bom and a cookie are present,
        but disagree, a SyntaxError will be raised.  If the encoding cookie is an
        invalid charset, raise a SyntaxError.  Note that if a utf-8 bom is found,
        'utf-8-sig' is returned.

        If no encoding is specified, then the default of 'utf-8' will be returned.
