Description NMONNET 2007-10-11 09:29:12 UTC
When enabling "justified paragraphs" in Wikipedia, I noticed that "fi" and "fl" ligatures looked wrong, the following characters overwrite it slightly.

(attaching pictures to demonstrate)

Note that this happens on:

* Gentoo ~amd64 Firefox 2.0.0.7, pango 1.18.2, dejavu 2.20
* Ubuntu Gutsy x86, Firefox 2.0.0.6, pango 1.18.2, dejavu 2.19-1ubuntu2

I should add that stock Bitstream Vera Sans do not display this problem.

Thanks for the bug report but this isn't a DejaVu bug. It just happens that DejaVu fonts trigger
the Firefox/Mozilla bug. Other fonts out there also have Latin ligatures, you can't expect them to remove ligatures just for a Mozilla bug.
The bug has been fixed in Firefox 3.0, so just wait for that version.

See https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/37828 (with a workaround for DejaVu 2.19) and
