--- Comment #4 from Rico kgbricola@web.de 2012-09-18 09:04:25 CDT --- Confirming. With wine 1.5.13 and with LANG=en_DK.utf8 wine notepad I'm not able to input any äöü.
I'm using Fedora 17, default keyboard layout is German. What's your distribution?
Using these work: en_AU.utf8, en_CA.utf8, en_GB.utf8, en_IE.utf8, en_NZ.utf8, en_US.utf8, en_ZA.utf8
These don't: en_AG.utf8, en_BW.utf8, en_DK.utf8, en_HK.utf8, en_IN.utf8, en_NG.utf8, en_PH.utf8, en_SG.utf8, en_ZM.utf8, en_ZW.utf8
