This is nothing to do with the format function. Chris, and JMF, is
talking about the internal representation of strings in Python.
Python 3.3 fixes a long-running design flaw that causes Unicode strings
to be buggy (the use of so-called "surrogate pairs" for characters
outside of the Basic Multilingual Plane), *and* saves up to 75% of the
memory used by strings (reducing it from up to 4 bytes per character to
as little as 1 byte per character), but at the cost of a trivially small
slowdown under some circumstances.
JMF is obsessed with the idea that Python is destroying Unicode for the
benefit of the Americans. It's quite sad really.
