Corrupted "W"

If you launch the Horn of the Abyss installer (a link provided), you can see
that the words "Welcome" and "Wizard" have a strange looking "W" in them. The
same issue affects the Etrom installer:

On Linux everything looks fine. I might be wrong, but I think this is not the
first time I see corrupted fonts on OS X. Maybe someone should check font
rendering on this system?

I've attached screenshots illustrating the problem. Installing "corefonts"
doesn't help. Nothing unusual in the logs.

OS X 10.9.5
