Well, this seems to be the best option but I was even afraid of suggesting it, as it means another dependency (and possibly a lot of work)

By the way, If you think it's ok, In the meantime we can have better precomposition support. I've attached Charset.cpp with the patched UnicodeCombine for full precompositions support (for 16-bit UCS canonicals only).

(I can also send the extractor code for uppbox if needed)

Best regards,
Oblivion

I am sorry to say that because it is mostly due to lack of docs, but I think all this is already better covered with

int UnicodeDecompose(dword codepoint, dword t[MAX_DECOMPOSED], bool only_canonical);
Vector<dword> UnicodeDecompose(dword codepoint, bool only_canonical);

- the reason why this was not quite documented is that above functions are sort of abandoned effort in previous attempt at better Unicode support. Anyway, they are using quite effective z-compressed table (as not to increase .exe size too much). This (and other) tables are producced directly from Unicode tables by uppbox/unicode. And they should also support more than 1 combining marks...
