[pypy-issue] Issue #3064: curses: get_wch return value inconsistent with cpython (pypy/pypy)

[Anthony Sottile]

New issue 3064: curses: get_wch return value inconsistent with cpython
https://bitbucket.org/pypy/pypy/issues/3064/curses-get_wch-return-value-inconsistent

Anthony Sottile:

```python
import curses

def c_main(stdscr):
    ch = stdscr.get_wch()
    assert isinstance(ch, str), ch


curses.wrapper(c_main)
```

Run this and type “a” on the keyboard

In CPython this does nothing

In pypy3.6 I get:

```shell
$ pypy3 t.py
Traceback (most recent call last):
  File "t.py", line 8, in <module>
    curses.wrapper(c_main)
  File "/home/asottile/opt/pypy3.6-v7.1.1-linux64/lib-python/3/curses/__init__.py", line 94, in wrapper
    return func(stdscr, *args, **kwds)
  File "t.py", line 5, in c_main
    assert isinstance(ch, str), ch
AssertionError: 97
```
