Names of places in different languages is often tricky. Do you write Munich when referring to the city in Bavaria? Or do you bother to write München referring to the city in Bayern, following the German spelling? Do you call that famous far east Asian country as Nihon instead of Japan? In the language of the country I came from (which is very, very far from both Russia and Ukraine), the spelling used for Ukraine's capital is Kiev, without any specific political connotation. It is the spelling I normally end up using without giving it much of a thought.
