Thanks!

Unfortunately, that is the problem.  `kiwi`, which is written in CPP, 
has a check for python version:

```
#if PY_MAJOR_VERSION >= 3
#define FROM_STRING PyUnicode_FromString
#else
#define FROM_STRING PyString_FromString
#endif
```

So it can handle Unicode, but has no way to know it *should* handle 
Unicode if we are using python 2.7 and `unicode_literals`.  I’ve 
opened [an issue with them,](https://github.com/nucleic/kiwi/issues/39) 
though of course if someone here had expertise in this it’d be very 
helpful.  Worst case scenario I can just cast every call to `str`, it 
just makes the code a bit of a mess.

Thanks a lot,   Jody
