You change the meaning of sys.stdout without flushing the previous
instance. So of course buffering can mess you up. If you want to
change the encoding, do it at the beginning of the script.

import sys, io
sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding="utf-8")

(You probably could use sys.stdout.flush() before reassigning, but doing
it at the beginning is better for several reasons.)
