I'd like to add something along these lines to the Release Notes,
under "Known Issues in the Release."

Please check for accuracy:

(I haven't tested this myself -- haven't reached this point yet in my
Windows setup!)


When using Python 3.6 or higher on Windows, the test suite fails to
run because of changes in Python's implementation of console I/O.

Several workarounds are available:


* Use Python 2.7, or Python 3.5 or below, or

* Run the test suite with the --log-to-stdout command line argument,

* Set the PYTHONLEGACYWINDOWSSTDIO environment variable before running
  the test suite, or

* Apply r1876707 and r[insert number here] and run the test suite.

This problem is (expected to be) fixed in 1.14.1.


Where "insert number here" would be Yasuhito's latest patch.
