\lyricmode and lyrics with numbers

[szelga]

i have a .ly file imported from musescore. it has lyrics on church slavonic
langiage which include numbers and other non-standard stuff (which, with proper
fonts is rendered as proper church slavonic text). here is an example:

ApartAverseA = \lyricmode { \set stanza = " 1. " Хва -- ли1 -- те и4 -- мz Го --
спо1  _ дне. А#л -- ли  _ лy  _ і -- а. }

of course this is not processed correctly by lilypond. can i somehow "escape"
these symbols to get a correct output?
