Created attachment 870161 [details] 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).
Hmm, this seems to only happen in Firefox. It renders fine in other browsers and in text editors.
I did quick analysis and looks like some important GPOS rules are missing. I will work on this next week.
I have fixed this issue and works fine at my end. Can you test LiberationSans*.ttf at http://pravins.fedorapeople.org/liberation/ and update me.
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.
Thanks for quick test. Sure, i will close this with next release.

@Pravin Satpute: Any update on releasing this upstream?
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle. Changing version to '28'.
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle. Changing version to '29'.
This bug has been fixed and waiting for upstream release for 3 year now. Can anyone assist here?
This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle. Changing version to 33.
It would be nice to make extensive uae of mark, mkmk and ccmp features to make diacritics freely to combine — so-called "dynamic diacritics". https://github.com/rsms/inter/issues/155
