(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...)
