Hmm, I can see only two diacritics in Kwrite with Code2000 font.
I found that you appended as many as five of them to each character
in your sample. What font did you use? Nonetheless, it's a pleasant
surprise that Kwrite does more than simple overstriking.

I think all it needs are encoded as precomposed so that
they don't need a special treatment other than the conversion between
NFC and NFD.

That's why Indic scripts are rather well supported in Yudit now :-)

It seems like this is where AAT fonts with state machine are superior to
opentype fonts.
