If it's really important, then look at the character metrics.  If you
just want a reasonable guess, you could look at the SPACING property
(see the XLFD for details).

Then, sorry, the font is not truly fixed-width; it contains at least
one zero-width character.  Of course, the server may be buggy and
returning a zero when it shouldn't - try examining the per_char
elements and see.  (If there are no per_char elements, and min_bounds
is not equal to max_bounds, something is definitely buggy.)
