Hmm, I can color combining diacritics separately in Opera, though it
doesn't use Uniscribe, so.

One thing I can't do, apparently, is make a [working] hyperlink out of
a combining character, though this is probably an issue with the font
not reporting the character having any space of its own.

A similar problem I have run across is that color as well as
hyperlinking dont play well with mandatory ligatures. If I have
an Arabic word starting with alif-lam-alif, I can't make a
link out of alif-lam by itself, or out of the rest of the word by
itself, without breaking the lam-alif ligature, though I admit
I'd have trouble figuring what the proper behavior in such a case
would be myself.

Suppose an Arabic text were to, for one reason or another, display
the al- in boldface, or red, or whatever--how would a professional
human (scribe, typesetter, signmaker, etc.) deal with the lam-alif?
