hopefully, the new code will be good enough to fully
replace the existing (pc)re and regex engines.  so as
long as you're not (ab)using some strange feature that
isn't covered by python's test suite, old code should
work just fine.

I'm speculating here, but I wouldn't be surprised if
the unicode support will appear in the CVS version
soon after the conference.

as for the official 1.6 release, only GvR knows...

python 1.6's unicode support will use 16 bits on
all platforms.

(if it's good enough for Java/Windows, etc...)

extending this for 32-bit characters shouldn't be that
hard, but I guess we have to wait for Python 2.0...
