Thank you for your information.

URW fonts seem to have been released several times.
http://git.ghostscript.com/?p=urw-core35-fonts.git;a=summary

I do not know whether or not those problems have been resolved.

However, there are still some problems.
e.g. http://bugs.ghostscript.com/show_bug.cgi?id=697058

So I think that LilyPond main font should be TeX Gyre fonts.
I'd like to use URW fonts in order to complement the missing glyphs.

This patch is only to set the font alias for the missing glyphs.

When you build current LilyPond, some TeX Gyre fonts are required.
They are installed in LilyPond's directory.
e.g. /usr/share/lilypond/current/fonts/otf

Do you think that URW fonts should be installed in the same directory?


Description:
Add Greek and Cyrillic glyph aliases

LilyPond default fonts (TeX Gyre) do not have Greek and Cyrillic glyphs.
New URW 35 fonts which are contained in Ghostscript 9.20 have them.

This commit makes that when you have the new URW fonts,
you can use their Greek and Cyrillic glyphs as default fonts.
