I'm using AS 5.1 with GateIn 3.1, defaultlanguage is german.
I can create a new user called "testwithäöü" and give him an emailadress "testwith@localhost" ("testwithäöü@localhost" can't be used) but when i try to login, there is an error message: "Sign in failed. Wrong username or password." and the username-textfield-value is "testwithÃ¤Ã¶Ã¼"
Another problem is the "SiteMap"-link in german. It is translated as "Seitenübersicht", but it is shown as "Seitenübersicht". So i checked all the *_de.properties, but there is the correct value "Seitenübersicht". I tried to fix it by setting the values in the propertie-files to "Seitenübersicht", but then it's shown much more wrong. If i create a new node and name it "Söhne", then it is shown correctly. ALL other ä, ö, ü works fine.
