open(sys.stdin.fileno()) is not guaranteed to work if the input or
output have occurred before. And io.TextIOWrapper(sys.stdin.detach()) is
not guaranteed to work if the input or output have occurred before.
sys.stdin internal buffer can contains read by not used characters.
sys.stdin.buffer internal buffer can contains read by not used bytes.
With multibyte encoding sys.stdin.decoder internal buffer can contains
uncompleted multibyte character.
