Huffman codes are conceptually isomorphic to arithmetic codes where all probabilities are 2^-k with k integer, so they have an obvious disadvantage due to more inaccurate symbol distribution.

Hopefully k is natural. ;)

Implied because any symbol distribution which probabilities do not sum to 1 is invalid anyway ;-)
