Unicode is simply code points. How the code points are represented
internally is another matter. The below code is from a 16-bit Unicode build
of Python but should look exactly the same on a 32-bit Unicode build;
however, the internal representation is different.
Python 2.6.1 (r261:67517, Dec 4 2008, 16:51:00) [MSC v.1500 32 bit (Intel)]
Type "help", "copyright", "credits" or "license" for more information.
However, I wonder if this should be considered a bug. I would think the
length of a Unicode string should be the number of code points in the
string, which for my string above should be 1. Anyone have a 32-bit Unicode
build of Python handy? This exposes the implementation as UTF-16.
