Looks like the charset defaulted to iso-8859-1 with the upgrade from 7.3 to 7.3.1.

Problem is that I don't remember what it was set to in 7.3. But I had no problems with foreign languages (Greek, Cyrillic and Chinese). If I just reset it to UTF-8 what problems will it cause, if any? Or is there a way to go and look what is stored somewhere in the database?
