Solution: change your username, use latin chars only.
It does not help (in XP at least).
Changing user name in "User Account Management" changes the name only remaing directory name intact. While the game doesnt like "wrong" characters in the directory title. So you need to do something with the directory: (1) create a new user with a "correct" name from scratch OR (2) rename c:\Documents and Settings\%User%\Local Settings\Application Data\Divinity 2\ so that %User% has latin characters only and replace one of ../ProfileImagePath registry key in some specific place so that it points to that new directory. That #2 way is rather risky and not recommended for newbies. It requires logging on a separate adminstrator account (different from one you gonna change) and some computer knowledge or you can break something.
