Variable-width encodings make many operations difficult, not the least
of which being "what is the code point for the ith character?"  The
benefit of going with a fixed-width encoding (like Python currently does
for unicode objects with UCS-2) is that so many computations are merely
an iteration over a sequence of chars/shorts/ints.  No need to recode
for complicated operations, no need to understand utf-8 for string
operations, etc.
