This is a neat idea, but encode spins forever when $num is negative and returns an empty string when it's zero. You could do this: 
    my $val = abs($num);
    do {
        push @ret, $chars[$val % $base];
        $val = int($val / $base);
    } while $val;
    push @ret, '-' if $num < 0;

But '-' is in the @chars array.
