The Problem is that composed characters like ä,ü, ... cannot be detected 
reliably in keydown and keyup events. In general any character that 
needs a compose key in any keyboard layout cannot be detected reliably. 
The keycodes generated for such characters depends on the keyboard 
layout. Therefore we decided to have consistent support for those keys 
that are reliable.

Do you realy depend on detecting those keys in keyup/keydown events or 
can you convert it to use keypress instead?

Best Fabian
