If you want to hear how much fun there is to be had in bolting on Unicode
semantics from a language level to a regular expression engine that doesn't
have them built-in, I'll buy Jarkko a double whisky and send him in your
direction. I don't think you really want that.
I agree we should have a black-box regular expression engine. I believe,
however, it should conform to Unicode Technical Report #18. Because believe
me, if it doesn't do so out of the box, there's no hope it ever will.
