    Many common string operations do not require indexing by character 
which reduces the impact of this inefficiency. UTF-8 seems like a 
reasonable choice for an internal representation to me. One benefit of 
UTF-8 over Python's flexible representation is that it is, on average, 
more compact over a wide set of samples.
