MATLAB *sometimes* prints non-ASCII characters in the command window

I have noticed a strange quirk where MATLAB sometimes prints non-ASCII characters in the command window. Specifically, the multiplication sign used to denote array size can be lower case "x" (ASCII code 120) or extended character 215. The latter looks very similar to the former in the command window and some text editors, but the extended character looks very different in LaTeX. I noticed this problem when copying part of the command window (or the diary function) to a LaTeX document: all arrays sizes in an object display are messed up, but direct display with the whos command works as expected. Here's a quick example.

classdef example
    properties
        Array = rand(100,1);
    end
    methods
        function object=example()            
            Q=evalc('disp(object)');
            fprintf('Object display: ');
            scanResult(Q);
            Q=evalc('disp(object.Array)');
            fprintf('Array display : ');
            scanResult(Q);
            
        end
    end
end

function scanResult(buffer)

value=double(buffer);
index=find(value > 127);
if isempty(index)
    fprintf('no extended characters');
else
    N=numel(index);
    fprintf('%d extended characters ',N);
    for n=1:N        
        k=index(n);
        fprintf('[%d -> %c] ',value(k),buffer(k));
    end
end
fprintf('\n');

end

For MATLAB 2019b and 2020a on a Mac, there is one extended character in the object display and none in the array display.
