needed: open source C/C++ regular expression library that does unicode

Question

I'm looking for a good open source C/C++ regular expression library that has full Unicode support.

I'm using this in an environment where the library might get ASCII, UTF-8, or UTF-16. If it gets UTF-16 it might or might not have the necessary quoting characters (FF FE) or (FE FF).

I've looked around and there don't seem to be any options other than PCRE.

My second problem is that I'm currently using flex to build some HUGE regular expressions. Ideally I would have a flex-like lexical expression generator that also handles Unicode.

Any suggestions?

Answer 1

Have you considered ICU?

It has mature regular expression support.
