IMO Python is doing exactly the same thing that Go does (I know too little about Rust to comment) the only difference is that Python respects the LANG variable while Go is just fixed on using UTF-8.

It doesn't. Go's internal string encoding is UTF-8 and it can even be malformed. 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.
Here's your problem: you should not care how python is representing it internally.

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.
