Latex编译错误

1、在Windows上可以运行的LaTeX文件放到Mac上报错，Package inputenc Error: Unicode character fi (U+FB01)(inputenc) not set up for use with L……

solution: 

U+FB01 is an fi ligature which should never be in your source file. So best would be to edit the input and replace it by fi but failing that

在文件首行加一行：

\DeclareUnicodeCharacter{FB01}{fi}
