I agree with n67 that it is a can of worms. Big, three-headed worms carrying guns and knives and having a bad disposition.

For me as someone who does not understand anything but the latin script, I want all non-latin names transcribed when I view the map. But when I’m in the place, it would be a good idea to have it in a way the locals will understand. I’m sure I would be understood better to ask for directions to Krásnaya plóshchaď than to the Red square.
