If someone is interested in suppourting UTF8, I recommend to use oniguruma.

http://www.geocities.jp/kosako3/oniguruma/

Oniguruma also supports UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE, etc .... And it is portable, it's available both on Unix and Windows.

So I think it is best regex C library to choose backend.

Sorry, I didn't explain this so well. I mean an decoder to marshal a C-string that I know is UTF8 into a Haskell String (i.e. [Char]). An FFI call out to C might be convenient, but will have overhead. It's not that hard to write a UTF8 decoder (and encoder) in Haskell; I just wanted to avoid wasted work.
