REALLY? Do we really want to encourage using bytes as paths? IIUC,
anyone that wants to platform-independentify that code just needs to
use proper strings (or pat glib) for paths everywhere, yes?
I understand that pre-surrogate-escape, there was a need for bytes
paths, but those days are gone, yes?
So why, at this late date, kludge what should be a deprecated pattern
into the Windows build???

Yes, this is good.

I'm really not sure utf-8 is magic enough to do this. Where do you
imagine that utf-8 is coming from as bytes???
AIUI, while utf-8 is almost universal in *nix for file system names,
folks do not want to count on it -- hence the use of bytes. And it is
far less prevalent in the Windows world...

Still think Unicode is the answer to that...
