About a week I was using KDE on a FreeBSD system without properly Cyrillic fonts installed. A little bit annoying.
To configure your system fonts install ports:
/usr/ports/x11-fonts/freefont-ttf
/usr/ports/x11-fonts/urwfonts-ttf
/usr/ports/x11-fonts/webfonts
/usr/ports/x11-fonts/xorg-fonts
/usr/ports/x11-fonts/xorg-fonts-cyrillic
/usr/ports/x11-fonts/xorg-fonts-truetype
Make sure, that you have in /etc/X11/xorg.conf:
Section "Files"
...
FontPath "/usr/local/lib/X11/fonts/TTF/"
FontPath "/usr/local/lib/X11/fonts/URW/"
FontPath "/usr/local/lib/X11/fonts/cyrillic/"
FontPath "/usr/local/lib/X11/fonts/webfonts/"
EndSection
After that you should run:
# fc-cache -v -f
The result is:
Have fun, guys! God luck :)
