• Using non ASCII characters in headers, like french ## Présence d'une DAACT, no longer causes an error in html_paged() for TOC processing (thanks, @sylvaine31, #339).
  However, this is recommended to always use ascii only id when possible to avoid issues or side effects. This can be done by specifying ID e.g. doing ## Présence d'une DAACT {#presence-daact}
