See here.

matplotlib/src/ft2font_wrapper.cpp

Lines 638 to 640 in f80d56e

size = PyUnicode_GET_SIZE(textobj);
codepoints.resize(size);
Py_UNICODE *unistr = PyUnicode_AsUnicode(textobj);

PyUnicode_GET_SIZE, PyUnicode_AsUnicode, and Py_UNICODE are deprecated.
We are planning to remove them in Python 3.11.

Please replace them with PyUnicode_GET_LENGTH, PyUnicode_READ, and Py_UCS4.

Is there a way to make the deprecations fatal at compile time?

The new macros were added in py33 so all versions of Python we support
have them.
