In Italy, most of the cities have the Italian name, some of them have an English name (Florence, Naples), some have a German name (Triest). The behaviour is different than OSM, at least for me.
- Naples is mapped with many names (https://www.openstreetmap.org/relation/40767), ‘Napoli’ being the standard one.
- Florence (https://www.openstreetmap.org/relation/42602) has ‘Firenze’ as standard name.
A renderer can choose which name to put as label on the map, usually it’s `name` or `name:locallanguage-abbreviated`.
