Yes, it solves that problem.  But that doesn't come without cost.

Most importantly, now Python writes illegal UTF-8 strings even if the user
chose a UTF-8 encoding.   That means that illegal UTF-8 encodings can
propagate anywhere, without warning.

Furthermore, I don't believe that PEP 383 works consistently on Windows, and
it causes programs to behave differently in unintuitive ways on Windows and
Linux.

I'll suggest an alternative in a separate message.
