Bug ID: 1076190 Summary: Rendering of Unicode tie bars could be improved Product: Fedora Version: 20 Component: liberation-fonts Severity: low 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 874108 --> https://bugzilla.redhat.com/attachment.cgi?id=874108&action=edit comparison between Liberation Sans and Helvetica
Description of problem: The rendering of the two Unicode tie bar combining characters (U+035E and U+035F) is not ideal. In particular the characters are quite short and far away from the characters they are tying together. This makes it appear more like a misplaced macron than a tie bar. The rendering in Liberation Sans appears to be equivalent to that of Arial which has the same issues. The rendering in Helvetica is better (see attachment 1).
In particular, because the under tie bar (U+035F) is so far away from the other characters, it sometimes gets clipped when rendered, as it appears to fall slightly outside of the bounding box for the line height (see attachment 2).
My suggestion would be to make the length of both tie bars slightly longer, and to move both of them slightly closer to the characters they are intended to tie together.
Version-Release number of selected component (if applicable): 12-Mar-2014 (2.x)
How reproducible: Always
Steps to Reproduce: 1. Install latest Liberation Sans (and Helvetica if you want to compare) 2. Go to https://www.mediawiki.org/wiki/User:Kaldari/Font_test_2
Actual results: Tie bars should be slightly longer and closer to the other characters.
Expected results: Tie bar are quite short and far away.
