STINNER Victor added the comment:
To debug this issue, it would help to have the following information:
- locale encoding: encoding variable
- tested character: ch
- character read by ncurses: read
Can someone reproducing the issue try to add: print("encoding=%s, ch=%r,
read=%r" % (encoding, ch, read)) before the error?
It may be an issue in the Python implementation of unget_wch() or get_wch().

Can we workaround this issue in Python? For example, use value & 0xffffff?

The test should be modified to use the encoding of stdscr, not the locale
encoding: encoding = stdscr.encoding. (In this test, both encodings should be
the same.)
