Going through the lang/python35 log, the following entry looks
particularly interesting:

----------------------------------------------------------------------
r444534 | dbaio | 2017-06-28 05:37:53 +0300 (Wed, 28 Jun 2017) | 29 lines

lang/python{27,33,34,35,36}: Make Python curses module work with Unicode
[...]
----------------------------------------------------------------------

And again guessing on the timestamps in your uname output, it could be
you are just missing this change.
