changing lyrics font

[Kai]

Hi Everybody,

is there a possibility to change the lyric font? I would like to add 
lyrics in hebrew and found out, how to 
include utf-8 in the lyrics. For better readability I need a hebrew 
font other then the standard. For 
\markup texts that works just fine. But in the \lyricmode it doesn't. 
Can anyone help me on that?

Using Version 2.15.38 with no problems so far.

thanks in advance!

Kai
