C can call Py_UNICODE functions with values > sys.maxunicode
Found when building scipy. Code that calls the
Py_UNICODE_IS* functions can use values
ch>=sys.maxunicode. In CPython these functions are switch functions with hard-coded values. PyPy calls into unicodedb, which does not protect from invalid values.
