孟加拉语书写与投影机中的多语

Question

我尝试使用多语用孟加拉语进行演示的包投影机：

\documentclass[10pt]{beamer}
\usepackage{polyglossia}
\setmainlanguage[numerals=Devanagari]{bengali}
\setotherlanguage{english}
\newfontfamily\englishfont[Scale=MatchLowercase]{Times New Roman}
\newfontfamily\bengalifont[Script=Bengali]{Bangla MN}
\title{\LARGE \textbf বong একাডেমী }

\author{Amit Majumder}
\begin{document}
    \begin{frame}
        \maketitle
        \tableofcontents
    \end{frame}


\end{document}

但它给出了错误信息：

Package polyglossia Error: The current roman font does not contain the Bengal(polyglossia) Please define \bengalifont with \newfontfamily. \select@language {bengali}

该怎么办？

Answer 1

它与 serif 选项一起使用，因为这样会使用罗马字体而不是无衬线字体：

\documentclass[10pt,serif]{beamer}
\usepackage{polyglossia}
\setmainlanguage[numerals=Devanagari]{bengali}
\setotherlanguage{english}
\newfontfamily\englishfont[Scale=MatchLowercase]{Times New Roman}
\newfontfamily\bengalifont[Script=Bengali]{Bangla MN}
\title{\LARGE \textbf বong একাডেমী }

\author{Amit Majumder}
\begin{document}
    \begin{frame}
        \maketitle
        \tableofcontents
    \end{frame}


\end{document}
