>>the troff was broken.

i'm not sure that's right; i think the problem lies elsewhere.
if it had been the use of that character, a better thing to do might have been to use \(<= so it
looks right when actually printed, or run through proof or page.  unfortunately
\(<= would produce a different discouraging effect in your case, so
there's little point in doing that.

actually, i suspect russ is elsewhere, but if not, it still doesn't
matter because it does work correctly at two other Plan 9 sites,
with that font= (and the ones i normally use).

if there is a problem, it might have been with the
font file (arguably all but special-purpose ones should have those
symbols), or perhaps with the troff configuration.
perhaps it's drawterm (seems possible to me, but i haven't yet booted Windows to try it).
might be something else, but nonetheless that original Unicode input is intended to work
(in Plan 9 troff).    /sys/lib/tmac/tmac.uni (which i think is undocumented)
is sometimes used by documents to get even more unicode to work.
the use of ≤ is built-in though.
