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.
