Font spacing

[Tom Vincent]

I'm having a problem with font spacing in urxvt. All characters seem
to have excessive white-space in between each other. I use DejaVu Sans
Mono (size 8) and there is a big difference between xterm and urxvt.

Heres a mockup of what I mean: http://i35.tinypic.com/qsmp.png

thread here: http://bbs.archlinux.org/viewtopic.php?id=44800)

My .Xdefaults looks like this:

urxvt.font:                 xft:DejaVu Sans Mono:size=8

Any ideas?
