I found an answer.  On github, isue # 1031
  pip install sympy==1.5.1

This solved the problem with octave 6.1.1 (hg id: 59696b24ea53) and 
newest symbolic.

Now, I have a printing problem.  from the example on github,

> pkg load symbolic
> syms x y z a b c k
> A = [[sin(x/2) floor(a^(x*c)); acosh(2*x/pi) ceil(sin(x/gamma(x)))]]
A = (sym 2×2 matrix)

  ⎡     ⎛x⎞      ⎢ c⋅x⎥   ⎤
  ⎢  sin⎜─⎟      ⎣a   ⎦   ⎥
  ⎢     ⎝2⎠               ⎥
  ⎢                       ⎥
  ⎢     ⎛2⋅x⎞  ⎡   ⎛ x  ⎞⎤⎥
  ⎢acosh⎜───⎟  ⎢sin⎜────⎟⎥⎥
  ⎣     ⎝ π ⎠  ⎢   ⎝Γ(x)⎠⎥⎦

Here, cut and paste shows the correct characters.  However on my xterm, 
in octave, most of the characters show up as a 'dot-box' character.  I 
seem to remember a simple fix, but, what?

Any ideas
