Details:

Windows 10 64-bit, Octave precompiled binary.

This Unicode display error is different from bug #47571 and others, because in
this case the *editor* can display Unicode properly but the *command window
fails*. It's narrower in scope and likely easier to fix.

See below:

Copy-paste from editor:


# function to display a 3x3x3 Rubik's cube as a cube net
function dispcube (p, colors = num2str((1:54)',"%02d")) # p is a permutation,
colors = a set of color labels
  assert(length(p) == 54);
  assert(all(sort(p) == (1:54)))
  assert(size(colors,1) == 54);
  colors = colors(p,:);

  fprintf(1, "              
╔════╤════╤════╗\n");
  fprintf(1, "               ║ %s │ %s │ %s ║\n", colors(7,:),
colors(8,:), colors(9,:));
  fprintf(1, "

  fprintf(1, "               ║ %s │ %s │ %s ║\n", colors(4,:),
colors(5,:), colors(6,:));
  fprintf(1, "

  fprintf(1, "               ║ %s │ %s │ %s ║\n", colors(1,:),

colors(30,:));
  fprintf(1,
"╚════╧════╧════╬════╪════╪════╬════╧════╧════╩════╧════╧════╝\n");
  fprintf(1, "               ║ %s │ %s │ %s ║\n", colors(46,:),
colors(47,:), colors(48,:));
  fprintf(1, "

  fprintf(1, "               ║ %s │ %s │ %s ║\n", colors(49,:),
colors(50,:), colors(51,:));
  fprintf(1, "

  fprintf(1, "               ║ %s │ %s │ %s ║\n", colors(52,:),
colors(53,:), colors(54,:));
  fprintf(1, "              
╚════╧════╧════╝\n");

endfunction



Copy-paste from command window, where the output is garbled:

How to make the command window use the same font display settings as the
editor?
