Bug ID: 1072095 Summary: Liberation Sans renders most Latin combining characters incorrectly Product: Fedora Version: 20 Component: liberation-fonts Assignee: psatpute@redhat.com Reporter: rkaldari@wikimedia.org QA Contact: extras-qa@fedoraproject.org CC: fonts-bugs@lists.fedoraproject.org, i18n-bugs@lists.fedoraproject.org, petersen@redhat.com, psatpute@redhat.com

Created attachment 870161 --> https://bugzilla.redhat.com/attachment.cgi?id=870161&action=edit Comparison between Helvetica, Arimo, and Liberation Sans

Description of problem: Liberation Sans renders most Latin Unicode combining characters incorrectly. These are the diacritics and tie characters in the Unicode range U+0300 to U+FE2F (https://en.wikipedia.org/wiki/Combining_character). In particular: 1. The diacritics do not take into account the width or height of the paired character (which I imagine is a kerning issue) 2. Tie characters are always positioned incorrectly. They are supposed to visually tie two characters together, but in Liberation Sans they are simply centered under the 2nd character.

Version-Release number of selected component (if applicable): version 2.00.1

How reproducible:

Steps to Reproduce: 1. Install Liberation Sans 2. Go to https://en.wikipedia.org/wiki/User:Kaldari/Font_test

Actual results: Diacritics and ties are a mess.

Expected results: See Helvetica example in attached file.

Additional info: The best way to understand this bug is to look at the attached file (comparison.png).

--- Comment #4 from Ryan Kaldari rkaldari@wikimedia.org --- That looks great! I have a few suggestions for tweaking individual characters, but I'll file those as separate bugs. I think you can close this bug as FIXED.

--- Comment #6 from Fedora End Of Life endoflife@fedoraproject.org --- This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'.

Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

--- Comment #7 from Fedora End Of Life endoflife@fedoraproject.org --- Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
