typically you would use $encode( , m) to transform an arbitrary string of text into a (nearly) alphanumeric string that's safe to pass around mIRC without worrying about undesired evaluations. then $decode( , m) can be used to perform the reverse operation
however, all this might be unnecessary. what reason do you have to want to replace all these characters? are you, by any chance, storing lines in a text file then later retrieving them with $read(), only to find that it's being treated as a line of code? if so, you should include the 'n' switch in $read(). there might exist other similarly easy workarounds depending on the nature of your problem
