Hi, I have this little routine that works great at finding and removing bad encoding (for my purposes): 
sub _checkit {

        my $txt = shift;

        use warnings FATAL => 'utf8';

        1 until eval {
                print "$txt\n";
                1;

        } or do {

                my ($charcode) = $@ =~ /U\+(\S+)/ or die $@;
                $txt =~ s/\x{$charcode}//g;
                0; # Try again!
        };

        return ($txt);
}

I have two questions about this:
  1. I think I understand, but I'd like a good explanation: Why do I need to print to generate/catch the error?
  2. Is there another way to do this (without print to stdout) so that it doesn't generate all the output? Or should I just redirect stdout to /dev/null?
Thanks!
