Hmm.
AFAIK, Unicode can't do color. I remember someone mentioning that
once. But someone who knows the exact rules can explain better.
Actually, the example given by Stephen does not need a "fill color",
but can be handled by a "ligature" glyph... given, that we _can_
reduce the logical relations to a certain number, and not have
arbitrary x,y-placement-coordinates. I still firmly believe this
should be possible, but I'm not an expert of the matter, at all, and
will be happy to be proven definitely wrong.
