Yes, well, Europe is a particularly bad case, because they all have
local names for each others' locations.  I rather doubt that the
same applies to Vancouver or Winnipeg or Iqaluit.

As I said before, you may want to apply your transliteration engine
when you know there's a script barrier.

Yes, that is the Right Thing.

Use the Olson name of the city in that case.  It's not ideal, but it
still helps a great deal.  (Transliterated when necessary.)

Not really.  The appropriate time for DST changes depends on latitude,
and in the Southern Hemisphere it goes the other way.
