HINT: IT'S FOR ALL VERSIONS!!!
Since there is a german translation in minecraft the letter "ß" doesn't work on it.
This is a hig level bug because it's against the german spelling like "heiß" because "heiss" is not correct!
So please include this letter to version 1.7.x (client and also server) and higher (actually I using 1.7.4 and latest client)
