Hello,
If the original name of a city is in other script than Latin, then Ventusky shows it`s Latin transcript below the original name. For example from an Azbuka script to a Latin script in Eastern Europe.
Have a look at the attached screenshot showing Belarus. The Latin transcript names of the cities are instead of just always using an English transript, being translated using a mix of different languages, Polish, Ukrainian, Romanian and I think even Czech or Slovak language. You can tell by the special characters each of the particular languages is using...It is a complete mess...
