I stopped using Rstudio/R for a few months because my employer wanted to use other software. I updated R, Rstudio, and all my packages when I started using it again.
Now all of my Rmarkdown reports have unwanted pilcrow (¶) symbols in my YAML headers when I use CSS formatting.
Would someone please help me understand why this quirk is happening now? I'd really like to drop those symbols.
Also you got that because your code is not that correct. It was just hidden before. You don’t need html tag in your title and other fields. Especially because they will be already including in h1 or h2.
Those are in the HTML templates used by default, so you would need to change it or postprocess the HTML h3 is used for subtitles as you can see.
Next Pandoc version should have a no pilcrows by the way. But again, the pilcrows are there because the field value is parsed as blocks and not inlines only.
