Note that these results are not sufficient to recover the original character sequences. To recover the original character sequence we probably need to know which characters were used and the number of times each character appeared.
That's something of a problem because this algorithm, and the frequencies used, are both explicitly tied to the length of the character sequence being compressed. It doesn't work with pre-shared parameters unless you limit yourself to a fixed sized collection of characters.
