Worked flawlessly!

Just for the archives, here's how it looks like:

static int
Unpickler_init(UnpicklerObject *self, PyObject *args, PyObject *kwds)
{
    static char *kwlist[] = {"file", "encoding", "errors", 0};
    PyObject *file;
    char *encoding = NULL;
    char *errors = NULL;

    if (Py_SIZE(args) != 1) {
        PyErr_Format(PyExc_TypeError,
                     "%s takes exactly one 1 positional argument (%zd given)",
                     Py_TYPE(self)->tp_name, Py_SIZE(args));
        return -1;
    }

    if (!PyArg_ParseTupleAndKeywords(args, kwds, "O|ss:Unpickler", kwlist,
                                     &file, &encoding, &errors))
        return -1;
...


Thank you, Mark, for the tip!
