I am not 100% sure...

The quantifiers are "*", "+", "?" and the "{}" constructs and they seem
to work fine in Python...

As for the character classes/group/category/blocks, I was wondering if
they couldn't be described and generated with chargen.py.

A preparsing of the W3C XML Schema patterns could then be done to use
them.=20

What might be tougher are the features such as the complement of classes
(ex: [\p{IsBasicLatin}-[^\p{L}]]) which AFAIK is an extension over perl
regexps.
