Follow-up Comment #2, bug #41461 (project octave):

Michael, I did check.  See

>From matlab (online) documentation it treats char as unsigned 16 bit value. 
Octave (from what i can determine) treats char as unsigned 8 bit.

this patch removes the undefined result for negative inputs.   It also returns
255 for values > 255, rather than 0.   I believe these changes improve
compatability, within the octave 8 bit char type.

if my arguments above are valid, are there any technical issues with the
checks i have implemented?
