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.
Additional info: See attachments for more info.

--- Comment #2 from Ryan Kaldari rkaldari@wikimedia.org --- By the way, if you adjust the tie bar characters, you may want to look at the other tie characters at the same time to make sure they are all visually consistant:
Rendered: a͜a a͝a a͞a a͟a a͠a a͡a
HTML: a͜a a͝a a͞a a͟a a͠a a͡a
Unicode: U+035C U+035D U+035E U+035F U+0360 U+0361

--- Comment #3 from Pravin Satpute psatpute@redhat.com --- Agree with you !! We just need to make sure fixing this does not create any kind of regression.
I will fix this.

--- Comment #4 from Pravin Satpute psatpute@redhat.com --- In this example you have mentioned only about
"a U+035e a" , how about "a U+035e b"? same applies for f, d
Existing position of uni035F works fine even with a͞b
How helvetica rendering it?

--- Comment #6 from Ryan Kaldari rkaldari@wikimedia.org --- Created attachment 888126 --> https://bugzilla.redhat.com/attachment.cgi?id=888126&action=edit comparison with more characters
I've attached a new screenshot showing the combinations requested.

--- Comment #7 from Ryan Kaldari rkaldari@wikimedia.org --- I case you can't open that attachment for some reason...
Helvetica is rendering a͞b and a͟g the same as Liberation Sans except for the horizontal position. In other words, it crosses the b and g, which is fine I think.

--- Comment #8 from Pravin Satpute psatpute@redhat.com --- I tried to fix this in http://pravins.fedorapeople.org/LiberationSans-Regular.ttf and http://pravins.fedorapeople.org/LiberationSans-Bold.ttf
Issue after this fix is. 1. For low width characters like "i", "j", "l" tie bar will get merged with previous letter.
Please test this and let me know if this work fine. Presently only improved for latin small case letters "a-z"
Do give some reference from helvetica if issues.

--- Comment #10 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.
