Hello there! It seems that I am experiencing the exact same issue as the rest of the people in this chat. From the updated (Illustrator 28.5) and later all Greek Capital letters appear with accents and it's wrong. The biggest problem is by opening older artwork that consists writing with Capital lettering and it changes the whole text with accents. Also that means, that I can not update my illustrator and enjoy all the new features while this issue is a big one to deal with.
