OK. I did a trouble ticket. Turned out to be a permission problem.
So I can see and search the language files.
But now I can't find where to change the character set. Under "Language Editor" I searched all files for "character set", "iso", "utf" and "encoding" ("encode"). Nothing was returned. Search is working since I can find other things.
Ideas? I still want to switch back to UTF-8.
Thanks!
