Drat. This is kind of sick. At the same time, Interix used the
U+F0xx area as we do. That's why I chose this area, to be filename
compatible with Interix.

This is really tricky. A new mount point flag could be used to override
this behaviour on a per path basis. One problem is, the unicode ->
multibyte conversion when evaluating a symlink is done before it's clear
where the symlink target is. Only the string is converted and it might
be a relative path, so the code doesn't know where the target ends up.
And that's probably not all.
Is it really worth to add code to support a long deprecated Windows
service?
