Hello,

   I simplified the problem down to :

#+CAPTION: Org Mode works 99.99\% of the time.
#+BEGIN_SRC -n
// this is only a proof of concept
#+END_SRC

As soon as I put the percentage sign in the caption, the LaTeX export backend fails with this message :

org-latex-src-block: Not enough arguments for format string

I tried "%", "\%", "\\%", "%%"... nothing works !

If I get it wrong, sorry but please update the documentation accordingly, as I found nothing in the specs regarding this matter specifically.

My versions :
Emacs  : GNU Emacs 26.2 (build 1, x86_64-w64-mingw32)
of 2019-04-13
Package: Org mode version 9.4.6 (9.4.6-4-g093c94-elpa)

Thanks !
