        In ISO 10646, the positions with hexadecimal
        values 0000D800 - 0000DFFF, used in the UTF-16
        encoding of UCS-4, are reserved, as well as the last
        two code values in each plane of UCS-4, i.e. all
        values of the hexadecimal form xxxxFFFE or xxxxFFFF.
        These code values or the corresponding numeric
        character references must not be included when
        generating a new HTML document, and they should be
        ignored if encountered when processing a HTML
        document.
