我正在尝试使用一位用户与我分享的 beamer 模板。不幸的是，我在使用重音符号时遇到了问题（因为我用法语书写）：似乎使用重音符号的字符会被忽略，不会显示在模板上。例如，输入：“Etalement à interface élastique”会得到“Etalement interface lastique”
我使用这个 sty 文件：名为“YTU.sty”

有人能帮我解决这个问题吗？
先感谢您，

删除\UseRawInputEncoding，就这样。
如果你查看文件.log，你会看到

这精确的的目的\UseRawInputEncoding是逐字节吸收输入，而不假设任何编码；由于主文档字体（Computer Modern Sans）在 128–255 个位置上没有任何内容，所以就会发生这种情况。使用其他字体，您可能会得到任意垃圾。
删除错误的声明会产生
由于您用法语写作，您也应该重新启用\usepackage[T1]{fontenc}并添加\usepackage{babel}。
正确的法语拼写不是“Étalement”吗？我认为你不应该省略大写字母上的重音符号。
