Re: AW: Problem with `selnolig` package and multi-lingual documents

["R (Chandra) Chandrasekhar" <chyavana-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

After some experimentation, and viewing this discussion at TSE,

https://tex.stackexchange.com/questions/574047/lualatex-amsthm-polyglossia-charissil-error

and especially Davislor's solution, I have narrowed the cause of the 
error to a line in an include-in-header file of mine:

\defaultfontfeatures{Ligatures=TeX,Scale=MatchLowercase,Renderer=HarfBuzz}

When this was changed to

\defaultfontfeatures{Ligatures=TeX,Scale=MatchLowercase,Renderer=Node}

the original error, purportedly due to selnolig, disappeared, and 
compilation to PDF succeeded.

If _individual fonts_ require `Renderer=HarfBuzz` that should included 
in their individual invocations, as for example, in

\babelfont[tamil]{rm}[Renderer=HarfBuzz,Script=Tamil]{Noto Serif Tamil}
