Yes, and pyreadline/console.py should convert unicode to byte strings before
rendering them.  There are two possibilities to fix this with ctypes:
- The first one is to explicitely convert unicode strings.  The attached patch
  does that for the WriteConsoleA function.

- The second one is to let ctypes do it automatically by setting the .argtypes
  attribute on the functions that need to handle text; in this case ctypes
  automatically convert unicode/byte strings.
