Hi Robert,

I've now tried at home with my own computer (also running Arch) and got
the same issue so it is at least not machine specific.

I did that, and now it works just fine.  Is there something different
(except for the location) when installing a font by just copying the ttf
files to /usr/share/fonts/TTF/ and installing them with the Fonts tool?
I mean, now it works with the very same ttf files I've previously copied
to /usr/share/fonts/TTF/ (replacing the files installed by the Arch
package).

Hm, another minor thing: when I compare the rendering of the above
paragraph in gedit and emacs, there are slight differences for some
glyphs.  For example, the F in TTF is slightly higher than the Ts, and
the y is slightly lower than, e.g., an a or o.  In gedit, their height
is equal.

I think that's an indirect dependency of xorg-font-utils but I don't
know why that is needed.  I think, it isn't.  At least the installation
recipe just says "copy the TTF files to /usr/share/fonts/TTF/ and make
them readable".
