``%a`` will call ``ascii()`` on the interpolated value. This is intended as a debugging aid, rather than something that should be used in production. Non-ASCII values will be encoded to either ``\xnn`` or ``\unnnn`` representation. Use cases include developing a new protocol and writing landmarks into the stream; debugging data going into an existing protocol to see if the problem is the protocol itself or bad data; a fall-back for a serialization format; or even a rudimentary serialization format when defining ``__bytes__`` would not be appropriate [8].
The "use cases" you are enumerating for "%a" are chimeric. Did you *actually* do those things in real life, or are you inventing them for the PEP? Regards Antoine.
