目录中的编号不支持希伯来数字

目录中的编号不支持希伯来数字

我注意到以下奇怪的现象：当使用希伯来语作为主要语言和阿拉伯数字时，目录中的编号是正确的，但当使用希伯来语字母作为数字时，它不起作用，即目录中的所有数字/字母都相同（但在页面本身上没有问题）。这是为什么？如何修复？

答案1

这也许（我想礼貌一点……）是gloss-hebrew.ldf宏中的一个错误\hebrew@globalnumbers（如果这真的是一个错误，那么可能还有其他相同类型的错误）。

这是一个修复方法。我使用了 Mac OS X 上默认提供的字体。

\documentclass[14pt,a4paper]{scrbook}
%\listfiles % for help in finding in the source of the bug

\usepackage{fontspec}

\usepackage{polyglossia}

\setmainlanguage[calendar=hebrew,numerals=hebrew]{hebrew}

\makeatletter
\def\hebrew@globalnumbers{%
   \let\orig@arabic\@arabic%
   \def\@arabic ##1{\expandafter\hebrewnumber\expandafter{\number ##1}}%
   \renewcommand\thefootnote{\protect\hebrewnumber{\c@footnote}}%
}
\makeatother

\newfontfamily{\hebrewfont}[Mapping=tex-text,
                            Scale=0.80,
                            Script=Hebrew]{Arial Hebrew}

附言：结果可能不是预期的那样。我不懂希伯来语……

请注意，在中可以发现gloss-hebrew.ldf：

\def\hebrewnumber#1{%
   \if@hebrew@numerals
     \protect\hebrewnumeral{#1}%
   \else
     \number#1%
   \fi
}

whose\protect看起来很可疑（不需要），因为\hebrewnumeral在 中定义的babel-hebrewalph.def是通过 声明的\newrobustcmd*。

正如我在评论中提到的，这似乎是一种奇怪的政策。除了重新定义\@arabic这一点\arabic非常大胆之外，它还会破坏使用 LaTeX 计数器\arabic来获取明确数字的 LaTeX 软件包。

字体与该问题无关。

gloss-hebrew.ldf和 中也存在一些错误babel-hebrewalph.def，让我们来修复它们：
