Follow-up Comment #3, bug #42651 (project octave):

I agree that we should try to be consistent.

Note that


sort ([66, "A", 67], [66 65 67])


is the same as


sort ('BAC', [66, 65, 67])


since the conversion of the mixed numeric and character array happens when the
array is constructed.

For this particular example, maybe sort should warn when the two objects don't
have the same type?  I would guess this warning would need to be disabled in
"traditional" mode.

Also, this brings up a couple of other issues.  We already have an
"Octave:num-to-str" warning ID that is supposed to be enabled by default, but
I don't get any warning for the mixed numeric and character array
construction.

Also,


[ 66, "A", 67 ]


produces an sq_string object, not a dq_string.  I'm not sure why that choice
was made.
