        # In Python 2.6 and 2.7, the shlex source file is encoded in
        # 'iso-8859-1', and the `wordchars` variable is defined as a byte
        # string. This causes a UnicodeDecodeError to be raised when the
        # parsed content is a unicode object. The following fix resolves that
        # (... but it should be fixed in shlex...):

            # stripped, etc.), so the tokens are now either:
