The issue

console8x16 font, which is favorite by many konsole users is unavailable starting from Kubuntu Gutsy and on. The font file itself exist on the system at /usr/share/apps/konsole/fonts, but:

• The directory is not in fonts path
• console8x16 is bitmap font, i.e. excluded by default system font configuration.

The solution

Add this to ~/fonts.conf or /etc/fonts/conf.d/99-konsole.conf

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
 <dir>/usr/share/apps/konsole/fonts</dir>
 <selectfont>
  <acceptfont>
   <pattern>
    <patelt name="family" >
     <string>Console</string>
    </patelt>
   </pattern>
  </acceptfont>
 </selectfont>
</fontconfig>

Then run fc-cache -fv (or sudo fc-cache -fv if you edited /etc.. file)
