Yes.  Buy my problem is that I can only see it use od -a
I do not see it in VIM nor can I parse anything out of that file that is
printable using the following perl snippet

use strict;

my $file = $ARGV[0];

open I, "< $file" or die "$!\n";
my $b = undef;
while(read(I, $b, 1) > 0) {
        my $ascii = ord($b);
        if($ascii >= 32 and $ascii <= 126) {
                print "$b";
        }

}

I'm baffled as to how 'od -a' sees the number but using other means such
as grep, perl, vim I can't
