I spotted the following warnings when converting some texinfo to HTML (for Guix package descriptions).
;;; WARNING (Don't know how to convert *braces* to HTML) ;;; WARNING (Don't know how to convert dots to HTML) ;;; WARNING (Don't know how to convert i to HTML) ;;; WARNING (Don't know how to convert math to HTML) ;;; WARNING (Don't know how to convert tie to HTML) I'm not sure all the texinfo I was converting is well formed, but in all but the last 4 cases look possible to fix, and this patch might work. I wasn't able to get past running the ./configure script, so I haven't managed to test the changes. As for *braces*, I'm not quite sure what that relates to.
