Click on the diacritics that you see on a sign or elsewhere to generate a list of possible european languages This project only accounts for european languages it also uses only the lowercase variants of the letter, sometimes the uppercase variants vary significantly This is a tool primarily for geoguessr
NOTE: I missed ņ but if you see it it's only in Latvian Adapted from a spreadsheet I'd link it but scratch doesn't allow links You can find it by searching "a guide to european latin diacritics" in google
