There's another thread here that gives a good alias for this type of thing, but this should help you out too.
/ascii {
if (!@ASCII) { window -E @ASCII Times New Roman,11 }
var %ascii 1
while (%ascii < 256) { aline @ASCII $ $+ chr( $+ %ascii $+ ) = $chr(%ascii) | inc %ascii }
}
Keep in mind that if you want to type it in manually, you'd use ALT and the number pad. Let me give you some examples (based off of the font I normally use which is Times New Roman -
different fonts will display different characters):
In mirc, typing //echo a $chr(49) would result in:
a 1 (the number ONE)
If you then held the ALT down and pressed 0049 on your number pad, you'd see a 1 (the number ONE) in your editbox.
Another example:
In mirc, typing //echo a $chr(123) would result in:
a {
If you then held the ALT down and pressed 0123 on your number pad, you'd see a { in your editbox.
