I had the exact same issue as OP. Trying appres gave me no input & editres didn't help for me either (the other stack overflow question).

anyway, I used xlsfonts with trial & error to just find the font from the big list of fonts. It wasn't one of the nice simple font names like 9x15 or anything.

-misc-fixed-bold-r-normal--18-120-100-100-c-90-iso8859-9 

on my system defaulted to the nice large size and printed unicode correctly. to prove a point,

-misc-fixed-bold-r-normal--0-0-75-75-c-0-iso8859-9 

defaulted to a small size that could not even print the unicode (oddly enough right clicking to large made it match the latter font).

for me, it wasn't very intuitive and it would have been nice to have someone reassure me as I struggled that 2 fonts in the list may look nearly identical but can still be rendered differently by xterm for some odd reason.
