这是我的 MWE：

我主要尝试在包中使用 Computer Modern 的黑板粗体（）\mathbb和书法（\mathcal）字体，仅仅是因为我更喜欢它们而不是 Latin Modern 的字体（在那些特定情况下），但我仍然希望能够访问 Latin Modern 的黑板粗体和书法字体，因此需要和宏。LuaTeXunicode-math\newmathbb\newmathcal
从我的 MWE 来看，由于某种原因，我似乎在访问 Computer Modern 的书法字体时遇到了问题。
我读了这个 TeX.SX 答案但是当我使用时\setmathfont[range={cal}]{cmsy10}，我最终无法访问拉丁现代的书法字体，因为它似乎将每个书法字体全局更改为cmsy10：

我也读过另一个 TeX.SX 答案但是当我尝试它的方法时，我仍然无法同时使用 Computer Modern 和 Latin Modern 的书法字体：

出了什么问题？如何解决这个问题？
谢谢。

您的问题不太清楚，但这显示了拉丁现代数学 OpenType Blackboard 粗体和书法以及类型 1 AMS Blackboard 粗体和计算机现代书法。
