Forgive me if I am a bit too harsh here, but I am not sure your
answer helps a lot, Leif... We are not Apple, we're only the CSS WG
and we try to understand what we should do here if we should do
something. Reading the whole thread about unicode normalization in
www-style, I am under the impression that the only conclusion is
"this is a real and painful problem, and the experts of this problem
clearly tell us CSS alone cannot solve it". Correct ?
