Note that there is a subtle difference between this code and your original code. Your original code was validating new characters as they were added (and characters being deleted). This code validates the whole string, which I suspect is more likely what you wanted anyway. This way you can easily add range validation and stuff too.

Perl is Huffman encoded by design.
