LaTeX 错误：Unicode 字符

我昨天将我的操作系统换成了 Ubuntu 22.04，安装了 TeX Live，但不明白为什么它不能与俄语和乌克兰语言。我使用Sublime Text编辑器


\documentclass{article}
\usepackage[T2A,T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[russian,english]{babel}

\begin{document}
 
Текст

\end{document}

错误：

[Compiling /home/anmnv/Documents/text.tex]

TraditionalBuilder: Engine: pdflatex. Invoking latexmk... done.

Errors:

答案1

感谢@DavidCarlisle 的建议”我必须安装 babel 俄语“同时还要感谢@Rmano 关于“切换T2A,T1到T1, T2A”的建议（它确实有效）。所以我的解决方案是：

sudo aptitude -y 安装 texlive-lang-cyrillic

\documentclass{article}
\usepackage[T1, T2A]{fontenc}
\usepackage[russian,english]{babel}

\begin{document}
 
Текст

\end{document}

答案2

这对我来说在 TL 2022 上有效（Windows 10，但仍然有效）：

\documentclass{article}
\usepackage[english]{babel}
\usepackage{fontspec}
\setmainfont{cmunrm.otf}

\begin{document}
 
Hello, world! Привет, мир!

\end{document}
