[mythtv-users] Myth Frontend - problem with national characters ?

[Warpme]

Hi *

Just quick question:

I'm living in Poland. My MythTV (R5A22) is working beautifully. 
Myth database is filled with UTF-8 encoded XMLTV file.
Accessing shows listings via MythWeb gives proper national characters - 
so I'm assuming my XMLTV file has proper UTF-8 encodings.
Unfortunately Titles/Descr/ProgGuide. presented by MythFrontend on TV 
have wrong national characters.
Is it bug, or should I configure something in Myth ?
Maybe it is font problem ?

thx in advance for help !
