Hello list

A few months ago I wrote about mis-shaped glyphs (about which noone was able
to help).  I recently found out that the feta font itself is borked on my
Gentoo system (and I discovered the same errors in Debian Squeeze’s), both are
2.12.3 I think.  So I installed lilypond in my virtual Ubuntu; I know this
looks right because a friend uses it.

But alas, I had to discover thusly that the Ubuntu-lilypond doesn’t do kerning
as nicely as my Gentoo setup.  I am using TeX Gyre as default font, because
it’s a little nicer to look at.  Interestingly, the Gentoo-version has simple
ttf files of the font, whereas in Ubuntu the Gyre package installed a set of
otf files.

If I use the default lilypond CM font, the result looks the same for the two
systems, so the problem seems to be with how lilypond (or the underlying text
renderer) digests the external font.

See the attached minimal example and screenshots thereof for the difference:
- the space between W and a in Water
- the space between T and r in Translated
- the space between T and . in S.A.T.B.


PS about the borked font issue:
I copied all files in /usr/share/lilypond/2.12.3/fonts/ from Ubuntu over to
Gentoo and naturally the latter renders well now. But when comparing the two
version of, for instance, type1/feta18.pfb in a font viewer, I noticed that
the Gentoo version show slightly less spacing between some glyhps.
Could that be related, since on Gentoo the fonts are freshly compiled during
installation?


Thanks for any help here, even if it’s just for learning a bit about
lilypond’s internals, since the above workaround fixed the problem which
“drove” me to Ubuntu in the first place.
