New issue 1946 by brownian.box: Problem with kerning (Ubuntu, external
ttf/otf fonts)

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.
