Update: You now only have to type "/charmap". It will display the first 255 characters. The reason why you can't display more characters is because the characters beyond 255 are exact repeats and therefore inaccurate.

Note: The variables have been changed from global to local. This way, no "/unset" commands are needed.

alias charmap {
  var %loop = 255, %num = 0
  while (%loop > 0) {
    inc %num
    echo -a %num -> $chr(%num)
    dec %loop
  }
}
