Quoting Per Bjornsson:
Hi Per,
Strange. And, as you noticed, it only happens to the ö character,
not
e.g. ä. Perhaps it is some kind of problem with the Freetype autohinter
that is used?
It seems to be so; I don't see this on Debian, though. I'll
try to
figure out whether this is an upstream bug or a Fedora-related issue.
If you're in Germany, perhaps you could try rebuilding the
Freetype
package with the TTF bytecode interpreter turned on (apparently there's
a switch in the code; Apple has a patent on the TTF bytecode
interpretation so it's turned off by default, and an auto-hinting
algorithm is used instead.) If that helps it's really very likely that
it's the autohinter that is doing something wrong. I'll see if I can
find time to fiddle with this as well.
Rebuilding Freetype with the bytecode
interpreter enabled fixes it. Once
I'm sure it's not an upstream bug, I'll file a bug report against
Freetype.
Thanks for pointing me to a solution!
Regards,
Stefan
