Non-unicode (UCS8 slavonic) fonts

[Germain G. Ivanoff-Trinadtzaty]

Hello all you Lilypond users,

o  Is it possible to engrave (vocal) music with NON-UNICODE fonts for lyrics 
?
I try to engrave russian orthodox church music with the help of Lilypond. 
Most of my fonts are either non unicode, either not correctly handled by 
Lilypond. For example :
- UCS8 Irmologion font collection : special encoding for slavonic texts
- Elizabeth Old Russian : special encoding for old russian characters, and 
accent

o  I have a problem when using fonts Cambria, Candara, Consolas, Constantia, 
and even Minion Pro.
These unicode fonts include old russian characters, and accent (U+0301 or 
U+0341) But they are not handled the same way by Lilypond (or Pango ?)
If any of you experimented such troubles with accented cyrillic texts, 
please mail me.

Thanks,
Germain G.I.T.
