tex4ht：“footmisc”和“hyperref”中的“symbol”选项存在冲突

Question

看来该symbol选项会导致.aux文件无效，宏的定义\fnsymbol写在这里而不是当前脚注编号。应使用以下配置文件进行修复footmisc.4ht：

它使用\@footnotetext来自的命令定义latex.4ht并改变了一些东西：

\long\def\:tempc##1{\protected@edef\@currentlabel{\the\csname c@footnote\endcsname}%
    \anc:lbl f{footnote}%
    \Configure{newlabel}{\cur:th\the\csname c@footnote\endcsname}{\protect\p@footmisc@footnote{\the\csname c@footnote\endcsname}}

上述代码要求将计数器的值\c@footnote保存在.aux文件中。\Configure{newlabel}有两个参数。

第一个包含指向脚注的超链接：{\cur:th\the\csname c@footnote\endcsname}产生类似这样的内容：<a id='x2-1001f1'></a>。

\ref第二个参数包含应在命令中的文档中显示的文本： {\protect\p@footmisc@footnote{\the\csname c@footnote\endcsname}}。

我们想要{\p@footmisc@footnote {1}}向.aux文件中写入类似的内容，因此需要\p@footmisc@footnote使用命令来防止命令的扩展\protect，但脚注计数器需要进行扩展。

在最后一步中，\p@footmisc@footnote根据命令的当前值定义。如果使用了 Footmisc 包的或选项\thefootnote，则会重新定义。在这种情况下，它会打印脚注符号。否则，它会使用数字。symbolsymbol*

以下是更新的示例：

\documentclass{book}

\usepackage[symbol]{footmisc}
% \usepackage[]{footmisc}

\usepackage{hyperref}
\usepackage{lipsum}

\begin{document}

\chapter{Hello}\label{sec:first}

Maintext\footnote{Footnote
  \phantomsection
  \label{gtag:xxx}
  }

  Another paragraph\footnote{another footnote\label{gtag:second}}. First footnote reference \ref{gtag:xxx}

  \lipsum[1]

Hyperref 
\hyperref[gtag:xxx]{abcd} Something. Second footnote reference \ref{gtag:second}. Reference to the chapter \ref{sec:second}.

\chapter{World}\label{sec:second}
\end{document}

结果如下：
