Here's your problem: you should not care how python is representing it internally.
> Go in fact does pretty much what Python 2's byte strings were just that string operations such as converting to uppercase or iteration over runes understands UTF-8 and Unicode.
Why do you care about internal representation though, what are you gaining if Go's string and Python's str can express all characters. In Go you still need to convert string into byte[] when doing I/O.
