Dear Maintainer,

Please consider this rendering problem of an OpenType font in Gnome.
1) use the attached font or download and install from http://aghja.net/
b/Pecita-Latin.otf
2) use Gedit setting up this font and enter these symbols - "'^`~ - a
replacement font is used. It is the bug.
3) use LibreOffice to see the good rendering of these characters in
this font.
In the font these symbols are decomposed using a ccmp lookup table in a
space + the corresponding combining mark.

Regards,
Philippe
