No. It means that Unicode character classes don't work in SRE, for
ucs4 builds; this is http://python.org/sf/599377.

It is likely that it was me who introduced this bug, when I added the
optimization for large Unicode character classes, but I haven't found
the time to investigate that further, and may not be able to do so in
the coming months. Contributions are welcome.

What do you want to know? It parses the character definitions of XML
1.0 2nd edition, and generates sre definitions from that.
