As long as 'sans-serif' in normal in Gnome/Unity and the patch, changing language detection criteria, fixes the problem I can assume that the problem is that Qt's(KDE's) "lang" passed to font configuration xml's differs from one in GTK (Unity/Gnome).
I mean it turns out in /etc/fonts/conf.d/90-fonts-nanum.conf here: <test qual="any" name="lang" compare="contains"> <string>ko</string> </test> that "lang" for cyrillic(russian) contains substring "ko". So I think that the contens of "lang" in worth debugging. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase in Ubuntu. https://bugs.launchpad.net/bugs/990635 Title: Sans serif cyrrilic font in kubuntu 12.04 is bad To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/990635/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
