+unicodetype_db.h is a file that needs to be regened, but it not
+particularly trivial to regen. For the first build of Python,
+strip out any kind of unicode support that requires
+unicodetype_db.h indiscriminately.
+
+We are effectively restricted to ASCII characters with this change,
+but it works.
