One point is that it will be a pain to support development of
a Formulator that uses Unicode strings for both Zope 2.5- and Zope 2.6+.
Another point is that while Page Templates handle Unicode strings, DTML
pages don't. I think the sanest way to do Unicode properly in Zope at
the moment is to drop support for Zope 2.5 and DTML, but I'm sure not
everyone has that luxury :-)

It may be possible to make TAL.TALInterpreter.FasterStringIO handle
mixing Unicode string and traditional strings sanely. It would involve
replacing the inherited getvalue() method with one that catches the
ASCII encoding exceptions, converting these strings to Unicode strings
(by checking the RESPONSE headers for the expected character encoding,
or using a heuristic method to guess if you're feeling brave).
I haven't tried this yet, and fixing DTML is left as an exercise to the
reader :-)
