I'm not sure why you think this is fixable, given the comments on the
tracker. What is your plan?

Can I suggest you try to investigate it a bit yourself:
>>> sys.stdin
<_io.TextIOWrapper name='<stdin>' mode='r' encoding='UTF-8'>
So it's a TextIOWrapper from the _io module (which is really the
implementation of the io module). You'll find its source in
Modules/_io. TextIOWrapper objects are defined in Modules/_io/textio.c.
But as you know, they wrap buffered I/O objects, which are defined in
Modules/_io/bufferedio.c. In sys.stdin's case, the buffered I/O object
wraps a raw FileIO object, defined in Modules/_io/fileio.c:
>>> sys.stdin.buffer
<_io.BufferedReader name='<stdin>'>
>>> sys.stdin.buffer.raw
<_io.FileIO name='<stdin>' mode='rb'>
Regards
Antoine.
