在将 STIX2 与 LuaLaTeX 和 unicode-math 一起使用时，我发现诸如\hat或 之类的重音符号\bar未与字母正确对齐：
我没有注意到具有相同配置的 XITS 存在任何类似的问题……
有没有什么解决方法？我认为考虑到这种字体的相对流行度，应该已经存在某种解决方案了。
最小工作示例：
\documentclass{article}
\usepackage{unicode-math}
\setmathfont{STIX2Math.otf}
\begin{document}
\begin{displaymath}
\bar v
\end{displaymath}
\end{document}
