I think it's also to do with language skills and pragmatism. English is my mother tongue, I can read French so would probably have no problem entering place names in that language. Elsewhere becomes more problematic.
I have created profiles for a whole set of siblings including my husband's granny born, in the 19th Century, in Kobe Japan. (father was a British trader working there) I wouldn't know how to enter the location in the Japanese of the period . If I could, no relatives could read it.
It isn't any different to a person from Slovakia entering locations in his or her own language.
