Sometimes I'll insert a note in LaTeX to /sort of/ treat it like a footnote, but in a table. Then I'll just put the notes in an itemized list under the table like this:
#+begin_src org | something^{1} | *Notes* - ^1 this is a note about something #+end_src I'm copying/pasting from a previous Org document, so I know this used to work. Now, instead of a superscripted 1, it exports as 1 with a "hat" (accented one with tiny caret above the 1). I noticed the same for the ~ symbol. That used to just be an ugly looking tilde. Now it's an accent. There's surely variables to customize, but I wanted to report in case we want this as the Org-mode default. Thanks, John
