Thanks for your help with this!  Did I miss an email in between?  Here
are some unanswered questions that seem to be stopping progress:

1.  What is the oldest Windows release that can understand the "new"
BCP47 locale names, like "tr-TR" or "tr-TR.1452"?
2.  If we translate to BCP47 automatically, should we put the ".1452"
on the end?  What does it mean exactly?  What does it mean if you
don't put it there?
3.  Do the new BCP47 locale names give *exactly* the same results for
strcoll() and tolower() etc, as the old "Turkish*" style names?

With answers to those questions we might be able to ship some nice
built-in translations to get users out of this jam.  If there are
issues on those points, we might have to face some questions about
what the encoding is of the "Turkish_Türkiye.1254" string itself,
which is tricky for us for technical reasons, among other problems...
not sure.
