Hi everybody, I have finally added preliminary support for babel (as in LaTeX package) to the feature branch. it is activated by the #+LATEX_BABEL_LANGS header keyword, which substitutes the need for #+LATEX_HEADER: \usepackage[...]{babel} in the header. In addition to that, more complex font setups can be configured using the new variable `org-latex-babel-fontspec', which you can set in your init.el, as a directory-local variable or with an Emacs Lisp source code block in your org document.
With this, my guess is that lualatex/xelatex font control is complete. I'd really appreciate testing and feedback (especially if you are a linguist and produce multi-lingual documents), Best regards, /PA PS: I would like to reiterate my request for MWE's for babel on _pdflatex_. Currently, if you use this compiler, things should continue to work as they always have. But I'm sure some of you would like to see improvements there too, -- Fragen sind nicht da, um beantwortet zu werden, Fragen sind da um gestellt zu werden Georg Kreisler Sagen's Paradeiser, write BE!
