As such, it's your X input method that's alternating between the
upper-case and lower-case forms of certain Greek characters, which is
not in our bailiwick.  Please identify the input method enabled on your
system, so that we can place a meaningful description in PROBLEMS; in
the meantime, insert:

  Emacs.useXIM: off

into your ~/.Xresources or ~/.Xdefaults to install the change
permanently, then type:

  xrdb -merge ~/.Xresources

and I'm closing this bug.  Thanks.
