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.
