+Subject: [PATCH] Change String handlign in Python 3 to byte type
+
+The byte type allows raw binary data to be passed in from std::strings.
+It becomes necessary in the python to .decode('utf-8') in most cases,
+but allows the programmer to make the choice as to when and where the
+text is encoded in python instead of it being assumed it always need be.
+Use case - passing binary in a std::string containing 0xff and other hex
+to python, passing byte object from python to c++ std::string.
