AFAIU, it's definitely NOT the same problem.

I see no sign of such composition rules for Devanagai in
lisp/language/indian.el.  So it isn't a surprise that Emacs doesn't
display those sequences like you expect.

I will take a look at this when I have time, but please file a bug
report about this issue.  If you can include in the report the results
of running hb-view (from the HarfBuzz distribution) on the text
sequences you describe, that would help.

Thanks.
