使用 fixltx2e 时脚注中的 \textsection 行为异常

这是如何使用微类型通过 \fnsymbol 启用脚注的突出功能？，我的答案就在那里。

对我来说很好，直到我添加fixltx2e包。

我知道这个包改变\@fnsymbol了

\def\@fnsymbol#1{\ensuremath {\ifcase #1\or *\or \dagger \or \ddagger \or \mathsection \or \mathparagraph \or \|\or **\or \dagger \dagger \or \ddagger \ddagger \else \@ctrerr \fi }}

到

\def\@fnsymbol#1{\ifcase #1\or \TextOrMath \textasteriskcentered *\or \TextOrMath \textdagger \dagger \or \TextOrMath \textdaggerdbl \ddagger \or \TextOrMath \textsection \mathsection \or \TextOrMath \textparagraph \mathparagraph \or \TextOrMath \textbardbl \|\or \TextOrMath {\textasteriskcentered \textasteriskcentered }{**}\or \TextOrMath {\textdagger \textdagger }{\dagger \dagger }\or \TextOrMath {\textdaggerdbl \textdaggerdbl }{\ddagger \ddagger }\else \@ctrerr \fi }

这意味着现在\textsection用作脚注符号，并且它是唯一不突出的符号：

示例输出

我不明白 有什么特别之处\textsection，例如，当\textparagraph工作正常时。这种行为的原因是什么？我该如何解决？

答案1

该命令\textsection很特殊，因为与其他命令不同，它也存在于T1编码中（在 中声明t1enc.def，由 加载fontenc）。现在，当要求 latex 排版文本符号时，它将首先检查该符号是否在当前编码中声明，在本例中为T1。有两种方法可以解决这个问题：

  • 添加\textsection到T1集合中：
\SetProtrusion[context=footnote]
   {encoding=T1, family=lmr, series=m, shape=n, size=scriptsize}
   { \textsection={,650} }
  • 或者，这看起来更干净的方法，取消声明\textsection中的命令T1，以便使用来自的符号OMS（在中声明omsenc.def，由格式加载）：
\UndeclareTextCommand{\textsection}{T1}

另一点说明：尽管fixltx2e将脚注定义更改为使用文本符号而不是数学符号，但字形实际上仍然来自数学字体（OMS）。要真正使用文本字体中的符号，您可能需要另外加载包，并声明而textcomp不是 的突起设置。（ 的问题必须以与上述相同的方式解决。）TS1/lmrOMS/lmsy\textsection

虽然这对 Latin 或 Computer Modern 没有任何影响，因为数学和文本字体中的符号相同，但对其他不附带数学字体的字体（例如 Times New Roman）则有影响。如果没有textcomp，脚注符号将从 Computer Modern 中选择，这不是您想要的。

因此，总结一下，我建议执行以下操作：

\usepackage{textcomp}
\UndeclareTextCommand{\textsection}{T1}
\SetProtrusion[context=footnote]{font=TS1/*/m/n/scriptsize}{%
  \textasteriskcentered={,650},
  \textsection={,650},
  \textdagger={,650},
  \textdaggerdbl={,650},
  \textparagraph={,650},
  \textbardbl={,650},
  }
\SetProtrusion[context=footnote] % dummy declaration
  {font=T1/*/m/n/scriptsize}
  {  }
