The io.TextIOWrapper class initializes a codec.IncrementalEncoder and uses it to encode str, but it never calls the encoder's encode('', final=True). According to the docs https://docs.python.org/3.5/library/codecs.html#codecs.IncrementalEncoder.encode:  

``If this is the last call to encode() final must be true (the default is false).``

Without a call to encode('', final=True), codecs cannot be created that use codecs.BufferedIncrementalEncoder which depend on being called with final=True to flush any internal buffers.
