当尝试使用 LuaLaTeX 构建以下文档时，我的计算机运行失败，并出现标题中的错误：
\documentclass{article}
\usepackage{hyperref}
\usepackage{polyglossia}
\setmainfont{Gentium Plus}
\begin{document}
See also \href{https://en.wiktionary.org/}{Wiktio}.
\end{document}
奇怪的是，如果我将链接文本更改为Wikti，删除链接或使用其他字体，它就会起作用。
我曾是无法在 Overleaf 上重现它，所以也许它与我电脑上安装的字体有关？我尝试清除，~/.texlive2021/但没有帮助。
知道该消息的含义或如何解释它吗？

答案1
这是一个 luaotfload 错误，将在下一次 luaotfload 更新中修复，但在此之前，您可以使用 Node shaper 而不是 HarfBuzz 来解决它：
\documentclass{article}
\usepackage{hyperref}
\usepackage{polyglossia}
\setmainfont[Renderer=Node]{Gentium Plus}
