We discussed this bug at Red Hat bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=543906 and the fix
provided works for pango but fails in emacs. This request is to add
ccmp feature to m17n rendering engine.

Similar request for harfbuzz https://bugs.freedesktop.org/show_bug.cgi?id=27485

(I'm going through old bug reports that unfortunately didn't get any
response at the time.)

Looking at the redhat bug report in Emacs, it seem like the characters
are displayed correctly -- at least as far as I can tell from this:

--
  3. type ഡിസ്പ്ലെ (സ്പ്ലെ = unicode raw 0d38, 0d4d, 0d2a, 0d4d, 0d32)

  Actual results:
  സ്പ and ലെ displayed separately

  Expected results:

  സ് and പ്ലെ rendered separately
--

Has this started working better in the years since this bug was
reported?  (And Emacs uses harfbuzz in Emacs 27 now, so perhaps that
explains it...)

Yes, I think HarfBuzz gets this right.

OK; closing this bug report.  Please reopen if this is still a problem
in Emacs 27.
