I can reproduce it when I run Emacs with LANG=C, and try to
see the 5th (or 6th) different point where non-ASCII
charaters exist.  The calling sequence of read-coding-system
is this:

  read-coding-system("Select coding system (default mule-utf-8): " mule-utf-8)
  select-safe-coding-system-interactively(1 5557 (utf-8 ....))
  select-safe-coding-system(1 5557 nil nil "/tmp/fineDiffA155544eB")
  write-region(1 5557 "/tmp/fineDiffA155544eB" nil no-message)
  ediff-make-temp-file(#<buffer  *ediff-tmp*> "fineDiffA" 
"/tmp/fineDiffA155544eB")
  ediff-make-fine-diffs(5 noforce)
  ediff-install-fine-diff-if-necessary(5)
  ediff-next-difference(1)
  call-interactively(ediff-next-difference)

I don't know why ediff-make-temp-file is called, but perhaps
it should call write-region while binding
coding-system-for-write to `no-conversion' or `emacs-mule'.
