我在 Overleaf 中协作处理 LaTeX 文档，一些团队成员在标签中使用德语变音符号 (ä、ö、ü、Ä、Ö、Ü)。它适用于\ref：
\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage{cleveref}
\begin{document}
\section{Introduction}
\label{Ä}
\ref{Ä}
\end{document}
现在，我想引入 cleveref 并引用它们的标签，但 cleveref 无法处理这些变音符号。以下代码会导致错误：
\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage{cleveref}
\begin{document}
\section{Introduction}
\label{Ä}
\cref{Ä}
\end{document}
是否可以使用这些标签而不更改它们？我无法更改其他人的标签。如果不可能，我必须坚持使用\ref。
这是包含错误消息的日志：

I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
