Description Nils Philippsen 2006-07-06 09:12:53 UTC
When compared to the unaccented character "o", the accented "ö" is too thin.
While it uses the same horizontal space, it seems squeezed to the left margin.

What size in ppem, or font size with your monitor's dpi, does this occur at?

I cannot reproduce this bug. Are you using Fedora? If so maybe try to change the
hinting settings in the gnome font configuration tool, the autohinter is
probably misbehaving with the font at that size.

Btw, did you stretch the screenshot?
Comment 3 Denis Jacquerye 2006-10-25 05:01:15 UTC
Your screenshot looks like you're using the autohinter, if it is the case, it's
an autohinter bug.
Comment 4 Nils Philippsen 2006-10-26 07:34:29 UTC
Well, I'm using FC6 now on all of my machines and can't reproduce the problem
there. As for autohinting, I used and still use stock Fedora Core packages, so I
use autohinting if the FC packages use it as well.

If there isn't anybody else with this problem, feel free to close the bug.
Comment 5 Clemens Eisserer 2007-02-08 04:04:24 UTC
I've exactly the same Problem with FC6 on two different machines - however on my machines the umlaut o is not only renderd too thin but also the second dot is missing.

I am using rgb-subpixel-antialiasing and hinting style set to "full.

Comment 7 Denis Jacquerye 2007-02-08 04:11:04 UTC
In Gnome the fix for this auto-hinting bug is :
- go to Font Preferences
- in Details
- Change the Hinting from Full to Medium of Slight.

(oops, Denis was first in replying :-)

This is an autohinter bug, and unfortunately, we can't do anything about it. This bug should be fixed in FreeType instead (maybe their latest package fixed this?).

Possible options for you are probably using hintstyle "medium" if you want to keep using the autohinter (not sure if that would work, but IIRC somebody "fixed" it that way). Or you could enable the bytecode interpreter in FreeType and get the only correct hinting of the font (the technology may be patented by Apple and therefor Fedora doesn't enable it by default) -- you may need to recompile FreeType to do that, or maybe there's an rpm somewhere.

Please report the bug to the FreeType authors.

Greetings
Ben

OK, I'll post a link on their mailing list.
Comment 10 Clemens Eisserer 2007-02-11 15:33:15 UTC
could someone please try wether the problem also happens with freetype-2.3.1 (as far as I know FC6 uses Freetype-2.2.1).

The authors said it might have been fixed, but I don't have a development machine available and no way to install gcc+libs for at least a month.
