I have found no resolution of this problem after a considerable amount of
searching the internet, and a post at the wxmaxima forum (with no follow-up
whatsoever from anyone there). A couple of other things I noticed about the
lack of symbols in the output lines is that if I copy the output line to the
next input line, all the symbols are there, but again if I request the output
of the newly copied input line, there are no symbols. I mentioned that
clicking on the defined function name on the input line and pressing the F1 key
displays the full output line, with all symbols, in place of the original line
bereft of symbols. Also both maxima from the command line, and xmaxima from
the console have no problems displaying an output function definition or
variable expression.
I suppose that the next step is to remove fink's version again, and try
installing from the wxmaxima website. It is stated there that for Mac OS X:
wxmaxima 13.04.0 is included with Maxima 5.30.0. That line is apparently out of
date as the versions I have installed at present via fink are Maxima 5.32.1 and
wxmaxima 13.04.2. I am not sure, really, how such a reinstall might change
things.
Incidentally, in order to get gnuplot to work with wxmaxima and maxima, I
followed a suggestion from an old document at
https://pangea.stanford.edu/~schmitt/maxima.html. It suggested creating a
.maxima directory in my home directory, and in it a file maxima-init.mac with
the following lines:
gnuplot_command:"/usr/local/bin/gnuplot"$
draw_command:"/usr/local/bin/gnuplot"$
set_plot_option([gnuplot_term, aqua])$
Afterwards, plot2d worked fine from wxmaxima and xmaxima. Without this, the
plot2d output was being sent from wxmaxima to a file
/Users/home/maxout.gnuplot_pipes, which I think could then be plotted with
gnuplot (some of this has been lost to memory in the last few days).
If you have any other suggestions, they would be greatly appreciated. Thanks
again, Alexander.

I set via Preferences the fonts as you have them (and incidentally have tried
many, many others with no better results). The output seems to display the lisp
version of what I would expect (not that I know ANYTHING about lisp, mind you).
For example, if I define f(x):=x + cos(x), the output is ( ) := ( ), so
the operations of f, addition, and cosine, as well as the independent variable
name x, are missing in the output. If I now input f(%pi); the output is the
Greek symbol pi, some spaces and the numeral 1, rather than pi - 1 (the
operation of subtraction is missing in the output). Also, if I click on the
function name, and press the F1 key, the output line now displays as one would
expect, with both function name and independent variable x. What?
Even a simple input like (%i1) x + 2x; outputs the numeral 3 with no
independent variable x (I suppose a space follows the 3), but if I use the
evaluation operator on this input, that is, ev(%i1,x=3); the output is 9, as
expected. Wxmaxima is hiding something from me, isn't it?
