Comment #4 on issue 1312 by pnorcks: LilyPond may unrequestedly switch  
fonts when using non-roman scripts
http://code.google.com/p/lilypond/issues/detail?id=1312

This seems to be two bug reports in one:

1) The inclusion of a non-roman script in a string of text changes the  
entire font.
2) The rendering of one or more of the non-roman scripts is incorrect.

The first report about the font change *is* valid, but I would consider  
that a feature request; it would be nice if we could support multiple font  
families within a single piece of markup.  Pango supports a special syntax  
for manual, inline overrides using a PangoAttrList (see  
http://library.gnome.org/devel/pango/unstable/PangoMarkupFormat.html).   
Autodetection of outlier glyphs with Pango may also be possible, but I  
would have to look into it some more...

The second report is probably not valid (on the LilyPond side).  The  
original poster may have been using 2.12, which doesn't have the Pango  
fixes from 2.13, and there is a chance my recent fix for issue 1407 would  
improve rendering of the original poster's issue.
