The remaining question is what should be the type of the exception. ValueError is documented exception, but SystemError is actually raised exception (and it always was raised). PyUnicode_AsUCS4() is used 6 times in 3 files in CPython code, and it should never raise this exception. PyUnicode_AsUCS4() is in public API an can be used in third party code. Seems raising this exception can be caused only by programming error in C extension. SystemError is right exception in this case.

It looks to me that the code is correct and the documentation should be fixed to match the code.
