No checks are performed if the canonical representation has the correct character size; use PyUnicode_KIND()<http://docs.python.org/dev/c-api/unicode.html#PyUnicode_KIND> to select the right macro. Make sure PyUnicode_READY()<http://docs.python.org/dev/c-api/unicode.html#PyUnicode_READY> has been called before accessing this. New in version 3.3.
