the on text regex has no escape sequence, and we either need to use hex or octal to escape certain characters.
The bold part doesn't make sense
(it's understood though) but that last statement is not true, the only thing we need to do is by passing the way mirc parses a code.
Using hex or octal to match a colon inside the matchtext of an event's definition because you used the $ prefix is one solution, but you could also not use the $ prefix and use $regex without any hex or octal, I just wanted to make that clear.
