Run the following in *scratch*:

(make-directory "/tmp/emacs")
nil
(write-region "" nil "/tmp/emacs/ß")
nil
(write-region "" nil "/tmp/emacs/ẞ")
nil
(directory-files "/tmp/emacs")
("." ".." "ß" "ẞ")
(rename-file "/tmp/emacs/ẞ" "/tmp/emacs/ß")
nil

Note how `rename-file' has silently overwritten `ß'.  This is because on
macOS, `ß' and `ẞ' are different file names, but Emacs treats them as
equal.  Probably the test for case-insensitive file names should be
removed altogether (it can't work correctly and introduces a filesystem
race), and `rename-file' should use link(2) + unlink(2) if renameat2
isn't available.
