I have file debug3.org which contains only
* strange #+begin_export latex \[ \text{a_b} \] #+end_export Upon latex export (C-c C-e l o) the generated pdf shows a sequence of 4 "a subscript b" in a row (with 3 font sizes). Result observed with various Org versions including Org mode version 9.4.4 (release_9.4.4 @ /usr/share/emacs/27.2/lisp/org/) with 'emacs -Q'. NB: If I run pdflatex on the .tex created: pdflatex debug3.tex I get ! Missing $ inserted. <inserted text> $ l.31 \text{a_b} and no pdf is generated. -- EOST (École et Observatoire des Sciences de la Terre) ITE (Institut Terre & Environnement) | alain.coch...@unistra.fr 5 rue René Descartes [bureau 110] | Phone: +33 (0)3 68 85 50 44 F-67084 Strasbourg Cedex, France | [ slot available for rent ]
