I was thinking since i can never find the correct chr without having to go through them hundreds of times or without making a list (incomplete one) to make the $chr() feature work in reverse too.

Example: say i dont know what the chr for [ is (even though i do), i just simply type in //echo : $chr([) then hit the return key
the result would echo ": 91" that way i dont have to search for about 10 minutes just trying to find the correct chr code.
