Base64 is an encoding that transforms between 8-bit streams.
No, it isn't. What Stephen wrote above.
Either you get a "LookupError: unknown encoding: base64", which is what you get now, or you get an UnicodeEncodingError if the text is not ASCII. We don't want the latter, because it means that code that looks fine for the developer breaks in real life because the developer was American
That's bogus. By the same argument, we should suppress any encoding which isn't able to represent all possible unicode strings. That's almost all encodings provided by Python (including utf-8, if you consider lone surrogates).
I'm sorry for Americans, but they still must know about character encodings, and be ready to handle UnicodeErrors, when using Python 3 for encoding/decoding bytestrings. There's no way around it.
Regards
Antoine.
