I'd like to tell binary from text data (like the Unix file
program). Right now I'm using
my $c = shift;
my $cl = length($c);
return 0 if ($cl == 0);
my $t = $c;
$t =~ tr/a-zA-Z0-9//cs;
return ($cl - length($t)) < 100;
which obviously has a lot of room for improvements. Is there a CPAN module for this kind of thing?
