• It’s a dead script that was not that common in the first place, in Kievan Rus’ it was even used as a form of encryption in XI—XVI centuries for how little spread it was. It is also very different from modern Cyrillic. So, saying “most Slavs don’t know how to read it” is a bit of an understatement. Noone knows how to read it, apart from some linguists and overzealous Witcher fans.

    • It was widespread in Croatia until the late middle ages, about XIV-XV century.

      I could fluently read and write it in high school. Was bored.

        • Is it some kind of historical elective course

          No, there was a poster showing correspondence with Latin on the wall, somewhere. The symbols are almost 1-1 with modern orthography, so it takes only about a week of practice. And I was really bored.

          never seen Glagolic in the wild

          It’s about as distant from modern use as runes are for germanic speakers, but maybe with different connotations. Decorative nonsense.

          But I did submit essays written with that when I wanted to fail with style. :)

          I also met a guy in college who used it to keep notes. That guy was also bored.
