Perl still does have the best Unicode support, especially for regex's. In comparison, grep has imitation Unicode support (the -P "Perl" flag helps, but it's still nowhere near as powerful as Perl regex's). Python's standard regex library, re, is better than grep's regex's, but still not as good as Perl. Python also has a non-standard regex library, regex, in PyPi, which I think is as good as Perl. And yes, I deal with non-ASCII Unicode every day.
