        The argument has been percent-decoded and is now a byte string.

        a unicode string, but this may be overridden in subclasses.

        This method is used as a filter for both get_argument() and for
        values extracted from the url and passed to get()/post()/etc.

        The name of the argument is provided if known, but may be None
        (e.g. for unnamed groups in the url regex).
