Broken on 3.6
The current code always returns an empty answer on Python 3.6. This fixes it for me:

I only know python3 so I can't give good advice on making code that works on both 2 and 3. But a friend of mine's package has this function that you might find useful:

```
def to_native_str(value, encoding='utf-8'):
    if isinstance(value, str):
        return value

    if six.PY3 and isinstance(value, six.binary_type):  #pragma: no cover

    elif six.PY2 and isinstance(value, six.text_type):  #pragma: no cover                                                                                      
        return value.encode(encoding)
```
