Export Orgmode File In Chinese

OrgMode is really cool and export context to latex then processed to PDF is quite straightforwards. However when working with Chinese characters, I need additional packages.

First of all, install the following packages. (I already install the texlive package)

  apt-get install latex-cjk-chinese latex-cjk-xcjk texlive-xetex

Then in the org file, add the following latex options.

  #+LaTeX_HEADER: \usepackage{CJK}
  #+LaTeX_HEADER: \begin{CJK}{UTF8}{gbsn}

One drawback is the \begin{CJK} is added as a header option but it does not have close tag. I discovered this problem when checking with the tex output

People suggest to change to #+LaTeX: \begin{CJK}{UTF8}{gbsn} and append #+LaTex: \end{CJK} to the end of document.

It all works out OK except the title which is Chinese characters are not display at all.

Turns out XeLaTex has better support for UTF8. Actually I did not figure how to make it work in orgmode until a guy from orgmode mail list point out in this thread.

All I need to do is adding following option to the org document.

#+LATEX_HEADER: \usepackage{xltxtra}
#+LATEX_HEADER: \setmainfont{WenQuanYi Micro Hei}

Also need to customize emacs latex to pdf process.

(setq org-latex-pdf-process
      '("xelatex -interaction nonstopmode -output-directory %o %f"
        "xelatex -interaction nonstopmode -output-directory %o %f"
        "xelatex -interaction nonstopmode -output-directory %o %f"))

PS:

• The main font has been set may be vary among different systems.
• How I find a proper font under ubuntu is via command fc-list.

• This work in MacOS 10.15 in terms of chinese font.

  #+LATEX_HEADER: \setmainfont{STHeiti}
  

• ctex package also works besides xltxtra

  #+LATEX_HEADER: \usepackage{ctex}
  

• install ctex

  tlmgr install ctex
