Please post here the full output of "C-u C-x =" (from a buffer popped
up by Emacs) for these characters, both when you type them using the
appropriate input method and they are displayed correctly (as in 1)
above), and when you see them as empty boxes after revisiting the
file.  The differences between these two cases should give you a hint
what is wrong; if not, someone else here might have ideas.
