Install CJK Font

Use system font or install any CJK font. I recommend Sarasa Gothic (更纱黑体 / 更紗黑體 / 更紗ゴシック / 사라사고딕).

brew install font-sarasa-gothic

Convert the Notebook to PDF

1. Convert the notebook to tex

   1	jupyter nbconvert --to latex notebook-to-convert.ipynb

2. Modify the tex file to add CJK package and set CJK font

   Insert the 2nd and 3rd lines below into notebook-to-convert.tex. Make sure the font is available in system.

   \documentclass[11pt]{article} \usepackage[slantfont, boldfont]{xeCJK} \setCJKmainfont{Sarasa UI SC} \usepackage[breakable]{tcolorbox} \usepackage{parskip} % Stop auto-indenting (to mimic markdown behaviour)

3. Convert tex to pdf

   1	xelatex notebook-to-convert.tex
