i would add a running total of all characters seen as well, to facilitate calculating the actual frequencies, not just the counts.

    While I agree with you that such a total would be useful, it's clearly much cheaper to compute it at the end: 
        for my $symbol (keys %symbol) {
      $total += $symbol{$symbol};
    }
