e.g.

** +thing+ other things

is rendered literally, rather than having the strike styling applied to thing. Same for bold/italics/etc.

I tried this with both the current version and v1.13.2.1, but wasn't able to reproduce this.

$ echo "** +thing+ other things" | pandoc -f org -t native
[Header 2 ("",[],[]) [Strikeout [Str "thing"],Space,Str "other",Space,Str "things"]]

Which Pandoc version are you using and what's the output format?

it's in a reveal.js slide if that helps. I'm using cabal install pandoc v1.15.1.1. I'll add you to the repo so you can check

@tarleb I shared my slides with you, try doing this on the section titled Product (e.g. change to +Product+ HList)

Thanks for the sources, I can reproduce it now and am implementing a fix. A minimal version for this bug would be

echo "foo\n\n** +test+ testing\n" | pandoc -f org -t native
[Para [Str "foo"]
,Header 2 ("",[],[]) [Str "+test+",Space,Str "testing"]]

A (very hacky) temporary fix might be to use plain text as the first text in the header. E.g.
** <200b> +Product+ Hlist, where `<200b> is the zero-width whitespace (C-x 8 RET 200b). The extra space should be hardly noticeable in reveal.js.

Great, I'll try that! Any idea if you'll get round to the HTML attr parsing? That'd be awesome for setting background images.

I haven't really looked into it yet, sorry.
