Dear Monks, I throw myself on the altar for help on this one

I have the following hash: 

    my %key = (
    '1'=>'?', '2'=>'/', '3'=>'>', '4'=>'<', '5'=>':', '6'=>';',
       '7'=>'[', '8'=>']', '9'=>'{', '0'=>'}', '!'=>'p', '@'=>'o',
       '#'=>'i', '$'=>'d', '%'=>'j', '^'=>'h', '&'=>'g', '*'=>'k',
       '('=>'5', ')'=>'3', '-'=>'2', '+'=>'9', '='=>'%', '\\'=>'c',
       '|'=>'1', '~'=>'^'
);

And two functions,: 
sub decode {
    my $char;
    my $meta;
    foreach $char (keys %key){
       $meta =quotemeta $key{$char};
       $$message->{body} =~ s/$meta/$char/gis;
    }
}

[download]
and 
    my $char;
    my $meta;
    foreach $char (keys %key){
       $meta =quotemeta $char;
       $$message->{body} =~ s/$meta/$key{$char}/gis;
    }

But when it comes time to encode or decode a message like: this: ^5*9|1(1#|

becomes this: h:k{1?:?i1

ok, not problem, but going th reverse, this: h:k{1?:?i1

becomes this: \~5*9||5|#|

That's a problem ... can you help me understand why it's not doing the correct subs.

thanks, me
