Yes.

I get:

["-unknown-DejaVu Sans Mono-normal-normal-normal-*-12-*-*-*-m-0-iso10646-1" "DejaVu Sans Mono:pixelsize=12:foundry=unknown:weight=normal:slant=normal:width=normal:spacing=100:scalable=true" 12 14 0 0 0]

No, but 217/14 = 15.5, which is what image-size shows here.

I have DejaVu version 2.33, Freetype2 version 2.4.7, and
xorg-x11-libXpm-devel version 7.6.
