我知道fontforge可以用来检查*.otf和*.ttf文件的字形。
我还知道各种文档类别中使用的默认字体是Computer Modern。
我想检查我的 LaTeX 编译器默认使用的特定字体。我不了解 LaTeX 如何处理字体。根据常识，我认为每当我尝试编译一个简单的文档时，LaTeX 都会以某种方式访问默认字体，因此我创建了一个简单的文档（请参阅下面的第一个代码块）并尝试编译它。我曾经strace列出编译过程中读取的所有文件，但文件列表中没有包含任何扩展名看起来像字体的文件（请参阅下面的第二个代码块）。
\documentclass{article}
\begin{document}
abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
\end{document}
$ strace --output=/tmp/main.log --trace=openat pdflatex /tmp/main.tex
$ cat /tmp/main.log

我的问题是：如何找出系统中编译文档和查看 PDF 文件时使用的特定字体？
