We simply could not match Ruby regex exactly until we ported the same engines Ruby uses :( No two regexp engines have the same behavior, there's nothing anyone can do about that...
Well, the problems we ran into is that those behavioral differences hindered our ability to run stuff like Rails. We didn't really have a choice.
It looks like Oniguruma has a support for UTF-16 so I was thinking about using that in MacRuby. But as Oniguruma sees everything as a list of bytes, I do not know if you could use the Oniguruma UTF-16 support without modifying your Oniguruma port.
Yes, I have talked with Marcin about us doing a separate fork of "JOni" that works with Java's UTF-16 characters directly. I think it could become the best Java regexp engine. - Charlie
