That we need to support both unicode and bytes is important, but
already seems to have consensus. However, they present two distinct
* unicode text, presentable to the user, interacts with all manor of
* bytes, limited to local, internal use. Only approximated forms can
be presented to the user, only custom formats can be saved externally
None of the proposals have turned these into a single use case. All
they do is trade off various forms of subtly switch back and forth,
which leads to failure. Debating which subtle failure is better is a
Not only that, but we already have a solution that makes the choice
explicit, avoiding the subtle failure. This is the solution already
in use for os file & path functions. It's the solution Guido
