I need to convert tilde characters (\x7E) to a character pair (\x7D\x5E), but only if it's not the very last character. This bit fails: 
    $output =~ s/\x7E/\x7D\x5E/g;

because it also escapes the last character in the string. Can this be done with a regex, or should I just give in and write a loop?

Thank you.
Regards,
Rich
