Thank you. Did not know about that. It works, but seems for a specific char
or chars.

I have tried:

on mouseup
   lock screen
   repeat with i = 1 to the number of chars of fld "text"
      if char i of fld "text" is return then
         set the imagesource of char i of fld "text" to "myreturn"
      end if
   end repeat
end mouseup

but of course it is slow and would be slower if I want to replace spaces.

Additionally, if I cut and pasted in the field I need to replace the chars
in the pasted text again...

What I am looking for is a native replacement of a return, say, with a
visible characters wherever it appears.
