Problem with `selnolig` package and multi-lingual documents

Problem with `selnolig` package and multi-lingual documents

[R (Chandra) Chandrasekhar]

I am working on a multi-lingual document (English, Tamil, Sanskrit, 
Romanized Sanskrit, Greek). I have used pandoc to compile the source 
document perfectly into HTML, ePuB, and PDF via LuaLaTeX, until 
recently, when TeXLive 2022 was released.

The generation of the HTML, epUb and .tex files now proceeds without 
trouble. But compilation of the .tex file with lualatex produces a 
warning, and further forced compilation generates a truncated PDF file.

The operational error message singled out the package `selnolig`. I 
identified the following three lines in the default latex template and 
commented them out:

```
\ifLuaTeX
   \usepackage{selnolig}  % disable illegal ligatures
\fi
```

The document then compiles error-free.

I can modify the default template with every release to comment out 
these three lines, as I see no use for `selnolig` for my use case. The 
question is can this package be made optional, since it causes aborted 
compilation with multilingual documents.

Thank you.

Would be good to know the warning, and to have a mwe. Actually, if that package is to blame maybe open an issue there?

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

I get this warning when the .tex file generated by pandoc from .md is 
compiled by lualatex:
------
warning  (ligkern): error: 
...xlive/2022/texmf-dist/tex/lualatex/selnolig/selno
lig.lua:134: bad argument #1 to 'char' (invalid value)
.
<recently read> \endtemplate

l.760 \textsc{Word} &
                     \textsc{Meaning} \\
-----

An MWE would take more time to generate. I suspect that it happens with 
Romanized Sanskrit below the table headings shown above. It probably has 
to do with diacritics for Latin letters in a "kernable" combination.

I will post it when I isolate the text that causes the problem 
repeatably. I will also post it at TSE as you have suggested.

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

[R (Chandra) Chandrasekhar]

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}
