           Summary: Liberation Mono: incorrect spacing for Combining
                    Diacritical Marks.
           Product: Fedora
           Version: rawhide
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: medium
          Priority: low
         Component: liberation-fonts

According to the bug on freedesktop.org (link below), Liberation Mono has an
incorrect spacing definition for "Combining Diacritical Marks"; they should
have zero space, and should render above the last letter, not the next one.

Paste following text with selected font:

Correct: accent above o
Incorrect: accent above g


Reproducible: Always

Steps to Reproduce:
1. Enter a string with a combining diacritic mark in Liberation Mono, e.g.,
"o̍g". Don't use gnome-terminal; it relies on vte, which doesn't handle
combining characters. Use something like gedit; switching fonts will reveal the
issue as the diacritical mark switches places.
Actual Results:  
The diacritic appears one letter to the right of where it should be.

Expected Results:  
The diacritic should appear in the proper place.

I'm using ttf-liberation 1.04.93-1 on Ubuntu Intrepid; I'm filing this as an
upstream bug. If this should be filed elsewhere, please let me know.

I'm filing this because several monospace fonts have incorrect spacing for
"Combining Diacritical Marks":
