(How could non-3 Python have good Unicode support? :-) ) The default Python regexp gets into a tailspin on less well formulated regexps, which did work well with both PCRE and Perl 5. (I wrote an application (specialized query language) a few years ago where programmers entered regexps. Sometimes the execution just hanged. This was 2.6 and early 2.7.) I haven't tried the external regexp module, but hope it is better.
