Linux, perl v. 5.8.6 self-compiled - for what it can help.

In the first case you would be biten by the fact that the \xNN form works only when you have two hex chars, not three as in 092. So, the fact that you always get the same output is the real puzzle here.

#!/usr/bin/perl
use strict;
use warnings;
 
my $str = q|cat’s|;
printit($str, 'original');
 
(my $str1 = $str) =~ s/\x092/'/;
printit($str1, 'hex only two nybbles');
 
(my $str2 = $str) =~ s/\x92/'/;
printit($str2, 'seems good here');
 
(my $str3 = $str) =~ s/\x{092}/'/;
printit($str3, 'seems good here');
 
(my $str4 = $str) =~ tr/\x{092}/'/d;
printit($str4, 'seems good here');
 
sub printit {
        my ($v, $msg) = @_;
        my $h = unpack "H*", $v;
        $h =~ s/(..)/0x$1 /g;
        print "$h\t$v\t$msg\n";
}

__END__

0x63 0x61 0x74 0x92 0x73        cat?s   original
0x63 0x61 0x74 0x92 0x73        cat?s   hex only two nybbles
0x63 0x61 0x74 0x27 0x73        cat's   seems good here
0x63 0x61 0x74 0x27 0x73        cat's   seems good here
0x63 0x61 0x74 0x27 0x73        cat's   seems good here

Now, it would be good to see how this script runs on your machine, in particular to see the hex dumps. The comment messages will become wrong of course :)

Don't fool yourself.
