OK, I see this problem also bites us when generating png files for the
HTML manual. I think the following patch does what you propose above,
except it uses "*" instead of "default" to specify the default font.
If you think "default" is better, then it is easy enough to change.
Unfortunately, we still have the following problem:
../../run-octave -f -q -H -p /home/jwe/src/octave-trunk/doc/interpreter
--eval "plotimages ('extended', 'png');"

with font
We could avoid this problem by not including "png" in the list of
"enhanced" terminals, but I'm not sure that is the best solution. If
there is a symbol font that can be used with gnuplot's png terminal,
then I would simply use it. If this is possible, will someone please
explain how to do it?
I think we should leave the default fontname property value
"Helvetica". It is easy enough to globally change the default
property for all figures using
set (0, "defaulttextfontname", "*");
in your ~/.octaverc file.
