It seems that Tamil users expect computers to be able to do what they
could do with their manual typewriters, write vowels in a different
colour from consonants. For that matter Hebrew and Arabic users probably
want to be able to do the same (and the vowel colour may be "invisible").
But this is of course a matter between users of XML etc and W3C, and not
an issue for Unicode.

I may have missed or misunderstood the details, but it has been clearly
stated here in the last few days that (a) there are more than 11,000
redundant Korean characters in the BMP, and (b) many precomposed Korean
characters lack canonical or even compatibility decompositions which
would be desirable.

Yes on the latter part, if the users to whom the promises were made
don't actually want stability of errors!
