I think the source of the confusion is that it is described in terms of
UCS-2 and Latin-1, which people often think of (especially latin-1) as
different encodings rather than merely storing code points in a narrower
type.

Incidentally, how does all this interact with ctypes unicode_buffers,
which slice as strings and must be UTF-16 on windows? This was fine
pre-FSR when unicode objects were UTF-16, but I'm not sure how it would
work now.
