[issue38485] BUG Modules/_io/texio.c

[Jim Carroll]

New submission from Jim Carroll :

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.

Platform: Python 3.7.4 (tags/v3.7.4:e09359112e, Jul  8 2019, 20:34:20) [MSC 
v.1916 64 bit (AMD64)] on win32
