Aloha Nicolas, Using the filter you kindly provided (below) and this construct, "/Sida/ cf. /fallax/" I get the following incorrect LaTeX export, "\emph{Sida} cf.~/fallax/". I'm expecting "\emph{Sida} cf.~\emph{fallax}".
All the best, Tom #+name: ngz-nbsp #+begin_src emacs-lisp (defun ngz-latex-filter-nobreaks (text backend info) "Ensure \"_\" are properly handled in Beamer/LaTeX export." (when (memq backend '(e-beamer e-latex)) (replace-regexp-in-string " " "~" text))) (add-to-list 'org-export-filter-plain-text-functions 'ngz-latex-filter-nobreaks) #+end_src -- Thomas S.
