used

This is independent on the encoding !

Type following things in the console and see what happens for each case

  A) disp('é')  then Enter                             -> Everything is ok

  B) disp('é')  then 4 time BS  then 'a')  then Enter  -> Observe the result

         >> disp('a')
         error: parse error:

           syntax error

         >>> disp(''a')         
                          ^
                          
         i.e. The executed code is not the code display in the prompt
         
                 
  C) disp('é') then 4 time left arrow  then a  then Enter  -> Observe the
result

         >> disp(aé')
         aé

         i.e.  aé is displayed although the command appearing in the console
was invalid

     Then press up arrow and the previously executed command is displayed
(different than what was displayed)

 etc. etc.

 - sometimes the display is also disabled as posted previously
