Comment 2 for bug 1334495

Thanks for your report. I'm not sure about the affected packages, so let's wait with changing that.

The first thing I would like you to do to sort things out is to get a pure German locale. I'm not a Kubuntu user, and can't tell how you would do it via the GUI, but probably you can fix it by editing the /etc/default/locale file manually. Can you please edit that file so it only contains the line

LANG=de_DE.UTF-8

Then relogin and run the locale command. If the Chinese entries are now gone, please let us know if it made a difference as regards the mixed fonts.
