Sounds like yet another remnant of the old philosophy, which indeed supported encode and decode operations on both string types. :-(

No, that's something I explicitly readded to Python 3k, since the codecs interface is independent of the input and output types (the codecs decide which combinations to support).

The bytes and Unicode methods do guarantee that you get either Unicode or bytes as output.
