Correct. If you think this promise should be given explicitly in the
documentation, feel free to propose a documentation patch.

Of course, if the underlying (rather, encapsulating) PyObject goes
away, the pointer becomes invalid. IIUC, you have some guarantee
that the unicode object will stay available all the time.
