Once you're using pipes, you've given up any hope that the terminal will
report a useful encoding, so I'm not surprised you're getting None for
sys.stdin.encoding()

So you can either do as others have suggested, and guess, or you can get
the information explicitly, say from argv.  In any case you'll need a
different way to assign   encoding =
