如何使用 hyperref 在章节/部分名称中使用句子间距？

tag-icon • tag-icon spacing hyperref acronyms
如何使用 hyperref 在章节/部分名称中使用句子间距？

我使用 Vim + vimtex + latexmk + xelatex。当在章节名称中使用首字母缩略词时，Vim 会显示以下 lint：

Intersentence spacing (`\@') should perhaps be used.

梅威瑟：

\documentclass{report}
\usepackage{hyperref}
\begin{document}
\chapter{FOO: Bar}
Foo
\end{document}

如果我\@这样使用，则没有 lint：

\documentclass{report}
\usepackage{hyperref}    
\begin{document}
\chapter{FOO:\@ Bar}
Foo
\end{document}

然后hyperref抱怨：

那么我应该使用什么？或者我应该忽略或lint的hyperref投诉？

答案1

警告（不是错误）来自书签代码。空间因子的设置\@可用于 TeX，但不能用于书签字符串。可以通过以下方式禁用该命令：

\usepackage{hyperref}% option "pdfencoding=auto" or "unicode" recommended
\pdfstringdefDisableCommands{\let\@\@empty}
