Like I said, Eshell is not a shell, it just pretends to be one.  It
will eventually cause execve, or something like it, to be called, but
before it, the command-line arguments will be encoded in the locale's
encoding, since that's what execve expects.  This is true on Windows
and on Unix alike.  So in this case, the command-line arguments are
always "messed with" in Emacs.  If your locale happens to use UTF-8,
then it will _almost_ look as if the arguments were passed to execve
untouched, but that's an illusion, and is certainly incorrect when the
locale's codeset is not UTF-8 (which is always true on Windows).
