此错误一直出现：！包 inputenc 错误：使用的键盘字符在 inputencoding ansinew 中未定义

Question

我一直在处理这个文档，没有任何问题，但现在每次我编译它时，都会出现此消息：

! Package inputenc Error: Keyboard character used is undefined
(inputenc)                in inputencoding `ansinew'.

Answer 1

正如所发布的，您的代码是 UTF-8 的（因为整个网站都是 UTF-8），因此标题中的重音字母无法理解，而 LaTeX 期望如此ansinew

! Package inputenc Error: Keyboard character used is undefined
(inputenc)                in inputencoding `ansinew'.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.

? 

该错误来自于Í读回目录的时候。

删除损坏的.toc文件然后指定

\usepackage[utf8]{inputenc}

允许文档无错误运行
