我刚刚发现了 Latexdiff，它正是我现在需要的。但不幸的是，我无法.tex在我的计算机上编译 Latexdiff 创建的文件。我尝试了一个最小的例子：
文件编号 1：ori.tex
\documentclass{article}
\begin{document}
Hello World
\end{document}
文件编号 2：ori_v2.tex
\documentclass{article}
\begin{document}
Hello to this world!
\end{document}
它们都可以很好地编译。
但是，运行 Latexdiff 会产生以下文件，该文件无法编译：
\documentclass{article}

您以某种方式将 tex diff 文件保存为 utf-16。
^^@是 ascii 0 并且出现是因为对于\documentclass保存为 utf-16 的 ascii，每个其他字节都是 0。
通过将 diff 代码上传到此网站，您将其转换为 utf-8（整个网站都是 utf-8），因此您发布的代码可以正常工作，并且
