Well, you are the only person who is seeing this and it affects some basic
glyphs, so the problem is likely at your end.

Please run "fc-cache -fv" once in a console window. That should rule out all
caching problems.

Again, that glyph is correct in Mono and Serif and like the other glyphs they
haven't changed ever since the start of the project (except the double arrow).

Probably some caching problem then, fc-cache above should fix it...

Well, I hope you have some time, since so far you're the only person who's
experiencing this, so all we can do is give suggestions and ask questions to
you.

The final thing you can do is to manually install the 2.21 version of DejaVu
Mono from
http://prdownloads.sourceforge.net/dejavu/dejavu-ttf-2.21.zip?download with
KControl or whatever program Gnome uses (I think just browsing to "fonts://" in
the file manager and moving the fonts in place should work), make sure to run
"fc-cache -fv" after that and make sure to restart your programs as well.

If that fixes it, you've probably acquired some corrupt version from somewhere,
in which case it'd be nice to know where you've got it from.
