Calling detach() on the standard streams is a bad idea - the interpreter uses the originals internally, and calling detach() breaks them.

So, after much digging, it appears the *right* way to replace a
standard stream in Python 3 after application start is to do the
following:
sys.stdin = open(sys.stdin.fileno(), 'r',<new settings>)
sys.stdout = open(sys.stdout.fileno(), 'w',<new settings>)
sys.stderr = open(sys.stderr.fileno(), 'w',<new settings>)
sys.stdin = io.TextIOWrapper(sys.stdin.detach(), <new settings>)
sys.stdout = io.TextIOWrapper(sys.stdout.detach(), <new settings>)
...
None of these methods are not guaranteed to work if the input or output have occurred before.
