[applicative]

"→" is standard unicode; pandoc would have put it into the internal AST. If you were writing a pdf e.g. via pdflatex and tex fonts in olden times, a number of things might have gone wrong. Such a thing will pass unproblematically into the things like the going luatex - but similarly if you write the pdf via e.g. typst or one of the other engines.

It is true one ends up familiarizing oneself with peculiarities of the typesetting engine. The LLMs are lately teaching me bits and pieces about typst and typst+pandoc which I'm using for a writing project. They all seem infallible about pandoc curiosa.

Tables I agree are a nightmare in any plain text representation whatsoever - except with editor support which alas Word makes easy.
