I don't know what you'd constitute as a string into an int, but the char
one is easy --



unpack('C', $char);


	

If you're trying to do something like URI encode a string, this will do
it:


sub encode {
        $_ = shift(@_);
        s/(\W)/sprintf('%%%02X',unpack('C',$1))/eg;
        return $_;
}



And, to do things the other way, use pack.  eg, this will get rid of URI
encoding:
	
sub decode {
        $_ = shift(@_);
        $_ =~ tr/+/ /;
        $_ =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack('C', hex($1))/eg;
        return $_;
}
