screenshot of the font in question
Well, the problem doesn't seem to lie in the font, but in mkfontscale. Nautilus
with (I guess) freetype doesn't seem to have a problem with the font.

--- Comment #5 from Behdad Esfahbod <besfahbo(a)redhat.com> 2010-04-07 12:06:56 EDT

The font correctly follows the OpenType specification in defining 'name' table
entries in platform=3, encoding=0 (symbol) instead of platform=3, encoding=1
(Unicode). mkfontscale however seems to be unable to handle that.
The relevant parts of the spec are from this page:
http://www.microsoft.com/typography/otspec/name.htm
"""
When building a Unicode font for Windows, the platform ID should be 3 and the
encoding ID should be 1. When building a symbol font for Windows, the platform
ID should be 3 and the encoding ID should be 0. ...
...
Note that OS/2 and Windows both require that all name strings be defined in
Unicode. Thus all 'name' table strings for platform ID = 3 (Windows) will
require two bytes per character. Macintosh fonts require single byte strings.
"""
The following patch for mkfontscale makes it examine all platform=3 (Windows)
encodings. Fixes the problem in this bug and I don't expect it introduce any
issues. I do need to consult the OpenType mailing list though, since this part
of the spec is a bit contradictory.
Anyway, here's the patch for now. Should actually be safe to go in.

Ideally though, mkfontscale should be updated/rewritten to use fontconfig.
