如何在自定义环境中使用俄文字母？

我已经创建了以下文件

\documentclass[11pt]{article}

\usepackage{amsmath}
\usepackage[utf8]{inputenc}
\usepackage[T2A]{fontenc}
\usepackage{graphicx}
\usepackage[dvipsnames]{xcolor}
\usepackage{listings}
\usepackage[most]{tcolorbox}


\tcbset{
    codestyle/.style={width=0.9\textwidth,boxrule=0pt,colback=blue,arc=0pt,auto outer arc,left=0pt,right=0pt,boxsep=5pt,fontupper=\ttfamily, colupper=yellow}
}

\newtcblisting{code}{listing only, codestyle}

% Document
\begin{document}

    Пример кода:

    \begin{code}
        print("English comment"); // English comment
        print("Russian comment"); // Русский комментарий
    \end{code}

\end{document}

编码是无 BOM 的 UTF-8，但我可以使用我的编辑器（Jetbrains Idea）添加它。

不幸的是，当我尝试编译它时，它code只会在环境之外绘制俄文字母。

为何以及如何修复？

我已经在Windows下安装了MiKTeX：

包默认tcolorbox使用listings，它无法正确处理多字节编码。允许tcolorbox您指定将传递给列表引擎进行处理的单字节编码：listing utf8=cp1251。副作用 - 您还需要使用 babel 包指定语言。

\documentclass[11pt]{article}
\usepackage[T2A]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english,russian]{babel}
\usepackage{graphicx}
\usepackage[dvipsnames]{xcolor}
\usepackage[most]{tcolorbox}

\usepackage{amsmath}

\tcbset{
    codestyle/.style={width=0.9\textwidth,boxrule=0pt,colback=blue,arc=0pt,auto outer arc,left=0pt,right=0pt,boxsep=5pt,fontupper=\ttfamily, colupper=yellow},
    listing utf8=cp1251
}

\newtcblisting{code}{listing only, codestyle}

我已经为您制作了完全定制的文件，使用\lstlisting它很容易，然后您的列表使用tcolorbox（自己的想法）

在此处输入图片描述

\documentclass{article}
\usepackage[T2A]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage{listings} 
\usepackage{xcolor}

\begin{document}
\lstset{ keepspaces=true, 
backgroundcolor=\color{blue},  
showstringspaces=false,% for spaces between rus. words
language=C, 
extendedchars=\true,%for russian
framexrightmargin=0pt,
framexleftmargin=0pt,
framextopmargin=15pt,
framexbottommargin=15pt, 
frame=tb, framerule=0pt,
basicstyle=\color{yellow}\ttfamily\small}

\begin{lstlisting}
    print("English comment"); // English comment
    print("Russian comment"); // Русский комментарий
\end{lstlisting}

\end{document}
