I work in jupyter notebook and an error occurs when exporting a file to pdf. The Cyrillic alphabet is not displayed in the file. How to fix it?

我在jupyter笔记本上工作，在将文件导出为pdf时出现错误。西里尔字母表未显示在文件中。如何修复它？

I tried to create my own template, which is located in share\jupyter\nbconvert\templates\latex, but it didn't help.

我尝试创建我自己的模板，该模板位于Share\jupyter\nbConvert\Templates\LaTeX中，但没有帮助。

By default Jupyter uses XeLaTeX to compile latex files and to convert notebooks to PDF. XeLaTeX is an alternative LaTeX engine with inbuilt support of Unicode, while PDFLaTeX requires encoding tricks in order to emit characters in characters other than basic ASCII encoding.

默认情况下，Jupyter使用XeLaTeX编译LaTeX文件并将笔记本转换为PDF。XeLaTeX是一个内置Unicode支持的替代LaTeX引擎，而PDFLaTeX需要编码技巧才能发出基本ASCII编码以外的字符。

With XeLaTeX you do not need to load the fontenc package but you do need to ensure that the fonts XeLaTeX uses contain Cyrillic glyphs.

使用XeLaTeX，您不需要加载Fontenc包，但需要确保XeLaTeX使用的字体包含西里尔文字形。

Here is a modification of your template that uses Liberation fonts that contain Cyrillic letters. If you do not have these fonts (as you are probably on Windows) you might experiment with other fonts.

以下是对模板的修改，它使用了包含西里尔文字母的Liberation字体。如果您没有这些字体(因为您可能在Windows上)，您可以尝试使用其他字体。

((=- Default to the notebook output style -=))
((*- if not cell_style is defined -*))
((*- endif -*))

((=- Inherit from the specified cell style. -=))
((* extends 'base.tex.j2' *))

((* block docclass *))
\documentclass{article}
((* endblock docclass *))

((* block maketitle *)) ((* endblock maketitle *))

((* block packages *))
((( super() ))) % load all other packages

\usepackage{mathtools}
\defaultfontfeatures{Ligatures={TeX},Renderer=Basic}
\setmainfont[Ligatures={TeX,Historic}]{Liberation Serif}
\setmonofont{Liberation Mono}
((* endblock packages *))

To try this template you may run the following commands from the command line:

要试用此模板，您可以从命令行运行以下命令：
