Gvim Font-glitches for combining characters (pango-view has no problems) in "Ubuntu Mono" font #393
Description
What steps will reproduce the problem?
1.
Consider a text file with one line:
----á----
i.e. between the "minus signs": U+0061 U+0301 (g8: 61 + cc 81)
2. gvim -u NONE -U NONE -N -c 'set gfn=Ubuntu\ Mono\ 30'
What is the expected output? What do you see instead?
The expected output: the same es the output of
pango-view -t "----á-----" --font="Ubuntu mono 65"
There is a screen-shot attached with the output of Gvim and the expected output
(of pango-view).
This problem does not occur with e.g.
se gfn=Bitstream\ Vera\ Sans\ Mono\ Bold\ 12
What version of the product are you using? On what operating system?
Gvim 7.4.826 on Fedora 22
