This is really only academic fuzz: Python uses two bytes to store
Unicode code points -- it doesn't pay special attention to UTF-16
things like surrogates in the internals; only a few codecs do which
provide interfaces to the outside world.

BTW, PEP 261 uses the same terminology (UCS-2 instead of UTF-16)
and for the same reason:

         --enable-unicode=ucs2 configures a narrow Py_UNICODE, and uses
                               wchar_t if it fits
         --enable-unicode=ucs4 configures a wide Py_UNICODE, and uses
                               wchar_t if it fits
         --enable-unicode      same as "=ucs2"

If you're interested in more details, you should come to the
Unicode talk I'll give at EuroPython.
