As :c:func:`PyUnicode_AsUTF8AndSize`, but does not store the size.

.. note::

This function does not handle null bytes inside of *unicode*, so the length of the
returned string (from ``strlen()``) could be smaller than the length of the
passed unicode object, if the string contained embedded null characters. Prefer
:c:func:`PyUnicode_AsUTF8AndSize` when dealing with user input.
