[Python-Dev] PEP 383 (again) (original) (raw)

However, it is "mission creep": Martin didn't volunteer to write a PEP for it, he volunteered to write a PEP to solve the "roundtrip the value of os.listdir()" problem. And he succeeded, up to some minor details.

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.
