我需要有带数学字符的章节标题，但我收到很多此类警告

我用了这解决方案，但对我来说不起作用。可能是因为我使用的book是类而不是article？我该如何解决？
\documentclass{book}
\usepackage{hyperref}
\makeatletter
\pdfstringdefDisableCommands{\let\(\fake@math}
\newcommand\fake@math{}% just for safety
\def\fake@math#1\){[math]}
\makeatother
\begin{document}
\subsection{TE\texorpdfstring{\(_{11}\)}{11} }
\end{document}
这是我写这部分的方式
