Yes, but how would a unibyte string escape from C in the first place?
Does any of the functions involved encode file names by hand?

It's not easy to do, because this is the user's home directory, so you
need to have a user with a non-ASCII character in her name.  And the
C:/Users directory is not generally writable, or at least it isn't
supposed to be.

Why don't you ask that guy to install a development snapshot?  If the
problem persists, we can help him then.
