I still can't make up my mind.  I think the options are:

* Some sort of custom encoding (like you posted).
* Latin-1
* UTF-8 with surrogate escape encoding (and encouraging POSIX to change again)

What argues in favor of the last point is that many, many people are
using C.UTF-8 nowadays.  And effectively disabling wide/multibyte
conversion until you call setlocale does not seem particularly useful.

I have a feeling of déjà vu regarding this—I think I have investigated
non-setlocale defaults for wide/multibyte conversion in the past, but
can't find the previous discussion.

Thanks,
Florian
