http://docs.python.org/2/library/csv.html first says that Unicode input is
not supported then seems to suggest that UTF-8 is supported. Since the
UTF-8 encoding supports all of unicode, it's not clear what is meant by
saying it doesn't support unicode. Perhaps it means that there is some
specific encoding for unicode that is not supported (UCS-2, UTF-16)?
Can the documentation be updated to differentiate more carefully between
unicode and the encodings that implement it, and to specify which encodings
are not supported?
