Thanks. I invoked pandoc -f gfm MyDoc. -o MyDoc.pdf and in the resulting
PDF document the subscripts are still ignored. When running it with
--verbose in the resulting output I saw numerous instances of

[INFO] Not rendering RawInline (Format "html") "</sub>"
[INFO] Not rendering RawInline (Format "html") "<sub>"

However, when I added -t html5 to the invocation the diagnostics above
disappear, and the subscripts are indeed present in the converted PDF file.
Thanks for the tip - it has indeed improved things. Now it is still the
case that things like &mdash; or &Hscr; are ignored by pandoc. Any
suggestions on how to get pandoc to process them?

I am using the following:

pandoc 3.1.4
Features: +server +lua
Scripting engine: Lua 5.4
