This isn't entirely correct. It's true as far as most (but certainly not
all) filesystem implementations are concerned; but applications expect
to interpret those bytes in the context of the active locale.

Sure you do. How else are you going to know that the file is
unversioned? (The working copy database stores paths encoded as UTF-8.)

File names on disk DO NOT have to be represented in UTF-8. They do have
to be represented in consistently with the current locale settings.
A fairly plausible cause for getting the wrong representation is
changing the locale for the duration of a script invocation. Another
plausible way is to create files based on the contents of some script,
which are not encoded the as expected by the current locale.

Or the way you're using them, perhaps?

It's also too easy to ignore (or delete) files because someone managed
to misconfigure their locale. I'd really, really strongly suggest not to
make such a thing the default in Subversion.
