    Kent Karlsson called this an "ugly hack". CGJ is canonical
    combining class zero and a default ignorable code point.

    Does this mean that canonical ordering may ignore the
    CGJ and break the desired mark ordering anyway?

    What about OpenType GPOS look-ups? Would the CGJ break
    any mark-to-mark positioning?
