I've read all the references, and I don't understand why this issue is
in our bug tracker.  The referenced issues were raised against fonts
and/or shaping engines, and Emacs is just the user of those.  In
addition, my reading of the issues is that HarfBuzz processes these
scripts and fonts correctly, and since HarfBuzz is nowadays the
default shaping engine in Emacs (including on MS-Windows), Emacs
should be fine in this regard.

So I think there's nothing here for us to do, and I'm closing this bug
report.

Thanks.
