--- Comment #16 from Markus ldm@gmx.at 2012-09-20 09:10:27 CDT --- But that just creates an alias from en_DK.utf8 to en_DK.UTF-8 right? I ammended your lines to the file.
Then I did ~ ➜ locale-gen Generating locales... de_AT.UTF-8... done de_AT.ISO-8859-1... done en_DK.UTF-8... done en_DK.ISO-8859-1... done en_US.UTF-8... done en_US.ISO-8859-1... done Generation complete.
Then I tried both
~ ➜ LC_ALL=en_DK.utf8 wine notepad and
~ ➜ LC_ALL=en_DK.UTF-8 wine notepad
still broken.
