Yes, it is possible, but you do need your X11 system set up correctly for 
your UTF-8 locale (unstated).  It looks like you have no suitable mappings 
of UTF-8 fonts in X11, or you are running in a locale unknown to X11. (Try 
using en_US.utf8 to test the latter possibility.)  This is not an R issue.

Remote debugging of X11 problems is virtually impossible: please check 
with local expertise.
