I have different questions:
 - Should we trust PyObject_IsInstance() or PyUnicode_Check() (because they give different results)?
 - Should PyObject_IsInstance() and PyUnicode_Check() give the same result?
 - Should we fix the segfault?

To fix the segfault, I suppose that we use a more strict validation on the input type. Eg. Use PyUnicode_Check() instead of PyObject_IsInstance()?
