Makes sense to me. For want of a better metric, Google shows more
(English-only, modified in the last year) results for Uzhgorod than
Uzhhorod and more results for Zaporozhye than Zaporizhia. For
sufficiently obscure places, though, a most common English spelling must
be very hard to establish.

I guess the interesting thing about Kiev/Kyiv is that Ukraine wishes the
English spelling to be 'Kyiv', although 'Kiev' is of course much more
widely used.
