And I would take that over Py3 string mess. It could have been easily fixed by just setting the string encoding to utf-8.

No, you don't. If you're only using string operations for protocol-level stuff, like splitting the HTTP headers on a ":" character, then you can just treat strings as bags of bytes. Same for filesystem operations.

yeah, right. If you don't use strings ("just treat strings as bags of bytes"), then you don't need to use strings.
That's trivially true and I don't see the problem. Just use bytes.

That is correct. The problem is that the type for string literals in Python is, well, a string. It pops up in a myriad of places in the standard library.

For example, the exception message is (you guessed it) a string.

Well, I recommend you to try your own advice.
