james28909,AnomalousMonk thank you for sharing your thoughts. The methods that you have introduced can be used to escape the HTML metacharacter !. If I escaped the metacharacter ! for perl, using the code below,

$input =~ s/!/\!/g;

would it cancel out the effects of the method that you have introduced? Or is it enough to escape the HTML metacharacter ! and not to do anything with the perl metacharacter !? would that be secure enough as not to cause any malicious scripting by the user?
