Follow-up Comment #2, bug #26843 (project gnustep):

Yes, the latest version of Unicode.m has fixed the crash introduced in
r28328. Thanks!

Unfortunately, I'm now seeing a number of issues (about 60 of my tests are
failing) as a result of the changes made in r28335. I'm about to leave on
vacation for a week so I don't have time to track this down more specifically.
I'll look more closely at these issues after I get back and submit a new bug
if you haven't found and fixed something in the meantime.
