It shouldn't expect the surrogate pair but the single character string that
it actually gets, so it's the "expected" string that's broken here. Could
you check if the generated C code is the same on all systems? What does the
respective docstring part look like in the C code? Note that it is appended
to the string in the test code, I only need the short snippet above.
