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
