Dear friends,
I'm using lilypond inside a latex text. I tried in the
different ways explained in the Manual of lilypond but when
I compile the file
there are some problems with the fonts of the lyrics.
The lilypond file inside the file.tex dosn't show the fonts
with
accents.
In the single lilypond file I have no problem with those fonts.
Only when both lilypond and tex files are combined together it
happens.


How I can solve it?

Thank you for your help!
