Actually, it provided more than just Latin-1.  It provided all the
ISO-8859-X conversions.  And we did used to receive questions about
ISO-8859-7, for instance.

Well, we at Fourthought have moved on to Python 1.5.2, but as we all
heard from the responses to my question yesterday, some have reasons to
stick to Python 1.5.2 for now.

So I guess the big question is: for those sticking with Python 1.5.2, is
the old ISO conversion facility from xml.unicode still needed?
