`PyUnicode_AsUTF8` was not declared in this scope; did you mean `PyUnicode_Type`?

When building tree locally I get the following error saying PyUnicode_AsUTF8 was not declared in this scope; did you mean PyUnicode_Type?.

PyUnicode_AsUTF8 is part of the official Python C API, so this should compile AFAICT.

I will close the issue for now, but feel free to reopen if this is still an issue.
