Exporting unicode code-snippets to PDF from Org-mode

 | September 2, 2015 3:24 am

Since I started using org-mode some years ago, I’ve wound up using other document and prensenation tools (like LaTeX, Word, PowerPoint…) less and less. I find it the most convenient way of generating virtually any kind of document or presentation.

Now I’m working a great deal in Unicode. Org-mode itself has no difficult with unicode, but exporting to PDF goes through the LaTeX engine, and one has to do a little extra work to make sure that works seamlessly.

The simplest means I have found to getting LaTeX to interact correctly with Unicode is to use Xetex.  One needs to:

  1. Install XeTeX (use your system’s package management).
  2. Tell org-mode to use XeTeX when generating the PDF’s from the latex files — see the elisp snippet below.
  3. Remove inputenc and fontspec from the list of default packages that org includes when exporting LaTeX.

So  I added the following to my .emacs


;; fontify code in code blocks
(setq org-src-fontify-natively t)

;; Delete inputenc and fontenc from the default packages.
(setq org-latex-default-packages-alist (delete '("AUTO" "inputenc" t)
                   org-latex-default-packages-alist))
(setq org-latex-default-packages-alist (delete '("T1" "fontenc" t)
		   org-latex-default-packages-alist))
;; Add minted to the defaults packages to include when exporting.
;; alternatively you can add these by customizing org-latex-packages-alist.
(add-to-list 'org-latex-packages-alist '("" "minted") ("" "fontspec")

;; Tell the latex export to use the minted package for source
;; code coloration.
(setq org-latex-listings 'minted)

;; Let the exporter use the -shell-escape option to let latex
;; execute external programs.
;; This obviously and can be dangerous to activate!
(setq org-latex-pdf-process
'("xelatex -shell-escape -interaction nonstopmode -output-directory %o %f"))

 

You can find my emacs configuration on github.
