Description Paul W. Frields 2006-03-25 05:23:42 UTC

Description of problem:
Some spacing is off.  Capital "T" allows the next lowercase letter to be too
close using the "Normal" (i.e. non-bold, non-oblique) face.  I'm sorry I don't
know the technical terms for this anomaly.

Version-Release number of selected component (if applicable):
2.4-1.fc5

How reproducible:
Every time

Steps to Reproduce:
1. Set fonts to 10.5 or 11 points, for example
2. Look at words like "Tomboy" or "DejaVu".

  
Actual results:
Some capital letters are spaced strangely.  This seems like a regression from
the previous version since I just updated tonight and don't remember it
happening previously.

Expected results:
Nicely spaced letters

https://launchpad.net/distros/ubuntu/+source/ttf-dejavu/+bug/35470/

So this is an upstream bug. Not clear right now if the bug in in DejaVu, Pango
or fontforge

I'm going to sit on it some time while the situtation clarifies. I urge you to
do the tests proposed in the Gnome bug and report your results there so the
clarification goes faster.

I'd rather not do a rollback before we know what needs to be fixed for the next
dejavu release

Comment 2 Paul W. Frields 2006-03-25 12:01:28 UTC

Nicolas, it seems clear, especially from the last one you list:

  https://launchpad.net/distros/ubuntu/+source/ttf-dejavu/+bug/35470/

...that this is a Pango problem.  I installed freetype-demos-2.1.10-5.2.1, and ran:

  ftstring -m 'Terminal' 24 /usr/share/fonts/dejavu-fonts/DejaVuSans.ttf

Without using Pango, there's no kerning issue, results are similar enough to the
upstream bugs that there's no reason to upload additional screenshots here.  I'm
reassigning this bug to pango where it belongs.  Thanks for your help.

Comment 4 Nicolas Mailhot 2006-03-29 17:33:57 UTC

Since people in gnome bug seem to agree the short-term fix is to remove arabic
from dejavu (done in 2.4.1) and the long-term fix is to add opentype BASE table
support to FOSS font tools, I suggest to close this bug as upstream

Comment 5 Matthias Clasen 2006-06-20 05:11:48 UTC

Reassigning pango bugs to Behdad.

Comment 6 Behdad Esfahbod 2006-07-27 21:56:38 UTC

This is being tracked upstream, and dejavu has been fixed to not hit this bug in
the meanwhile.
