Are you able to think of any official language that uses these diacritics? Find out in this quiz!
If you have any more information that I missed, please let me know in the comments! I tried to research as much as I could, but I could've missed some.
Languages that use diacritics for loan words only aren't added
I noted a few remarks:
I believe that Dutch diacritics were forgotten, the diaereses and acute accents on most vowels.
Since this quiz is generalised to non-european languages, Turkmen should also be added in the diacritics (ç, ä, ž, ň, ş, ö, ü, ý).
Greek may however be removed in my opinion since it's a romanization of the alphabet.
