When I preview my R Notebook, the HTML output contains strange characters.

This chunk code and output

Chunk

gets rendered in HTML as

    Seems like a bug in the render process since the codes coincide with the text colors. Try to update RStudio, Knitr and Rmarkdown if not done already. – Martin Schmelzer Jun 7 at 11:58
  • I have the latest versions of R, RStudio, Knitr and RMarkdown. I've added part of the SessionInfo to my question. – Willy Jun 8 at 9:00
  • I've noticed that on RStudio Cloud I have the same problem. – Willy Jun 8 at 17:29
