We've been here before on r-sig-mac (which is the best place to 
discuss Mac-specific issues): UTF-8 is not a valid locale name.  To 
use X11 you need to set a valid locale, e.g. "en_US.UTF-8".

What we never found out last time was how this got set to the invalid 
value.

In any case the reason is clear: X11 looks for fonts encoded for a 
given locale, and has no fonts in that locale.
