Python helpfully uses a sensible locale when stdout is a tty but uses
the system (not the filesystem) default encoding, which may be ascii
and unable to encode some of the data we need to save. So brute force
kludge it to ensure sys.stdout.encoding is UTF-8 when writing the
output we'll read as UTF-8 anyway.
