It's true that this is to some extent subjective, but I'm afraid that's 
the best we can do.

By the way, end users should not need to deal with English-language 
strings like "Kiev". Instead, they should be seeing translations like 
"Київ", "基辅", and (my favorite) "Kænugarður". These translations are 
maintained by CLDR. See:
