whatever PyTypeObject's set to:

PyTypeObject
    The C structure of the objects used to describe built-in types.Unicode Type

These are the basic Unicode object types used for the Unicode implementation in Python:

Py_UCS4
Py_UCS2
Py_UCS1

    These types are typedefs for unsigned integer types wide enough to contain characters of 32 bits, 16 bits and 8 bits, respectively. When dealing with single Unicode characters, use Py_UCS4.

    New in version 3.3.

Py_UNICODE

    This is a typedef of wchar_t, which is a 16-bit type or 32-bit type depending on the platform.

    Changed in version 3.3: In previous versions, this was a 16-bit type or a 32-bit type depending on whether you selected a “narrow” or “wide” Unicode version of Python at build time.

PyASCIIObject
PyCompactUnicodeObject
PyUnicodeObject

    These subtypes of PyObject represent a Python Unicode object. In almost all cases, they shouldn’t be used directly, since all API functions that deal with Unicode objects take and return PyObject pointers.
    New in version 3.3.

PyTypeObject PyUnicode_Type
    This instance of PyTypeObject represents the Python Unicode type. It is exposed to Python code as str.
