* Use xelatex executable binary instead of the default pdflatex: `ConfigureMaTeX["pdfLaTeX" -> "/Library/TeX/texbin/xelatex"]` * Include support to Chinese text in the preamble via the option to MaTeX: `SetOptions[MaTeX, "Preamble" -> {"\\usepackage[UTF8]{ctex}"}]` * Verify: `MaTeX["\\text{之乎者也} \\sum_{k=1}^{\\infty} \\frac{1}{k}"]`
