Thanks. I've spent my entire week developing this.

Yes, I failed to take into account this possibility. (Although I'm 
actually a bit surprised about exactly where it fails - it should make 
it past that particular step OK.)

In fact it falls over if the input contains only one unique character; 
you can have twenty of them, it'll still fall over. It's a limitation of 
the algorithm, but the program should fail more gracefully than that.

(If you haven't tried it yet, it fails on empty input too.)
