Hey, I've got that bug on my desk right now (along with a number of 
other unicode problems in the Zope core.) I don't know what to do about 
it yet (I can't get to it until at least tomorrow), but I have a feeling 
that my solution is going to be a patch against the core.

Even if code generation could build 100 percent of the application, there will still be an endless supply of boring meetings about feature design."
