我可以减少嵌入字体的数量吗?

我可以减少嵌入字体的数量吗?

我的 63 页文档使用了四种不同的字体,Libertinus Sans、Libertinus Serif、Libertinus Math 和 Latin Modern Mono。它包含几个带有 Libertinus Sans 文本的图表,这些图表从 macOS 上的 EazyDraw 导出为 pdf 并包含在文档中\includegraphics。该文档是使用 lualatex 编译的。

输出的结果pdffonts令人吃惊的长:

问题:

  1. 为什么相同的字体/类型/编码组合(例如 LibertinusSerif/CID Type 0C/Identity-H)会出现两次?可能是字体大小不同?
  2. LibertinusSans 与类型/编码的不同组合似乎与所包含的图表有关。有没有办法“重新编码”以使字体更加一致?
