在 Index: 第一行和 \texttt 中打开（启用）全局连字

Question

hyphenation{}在 Index 的第一行和 \texttt 中不起作用。

我怎样才能打开它？

new column当连字功能打开时，我们该如何预防呢？

只有连字符的索引设置才是可取的。

基于以下MWE讨论了该问题：

当索引中的单词很长（连字符）时，删除（删除）意外的新行

自定义测试类型

附加问题“如何强制单词Newline不Einstein进入下一列？”可以使用此答案解决 https://tex.stackexchange.com/a/132415/44348

但是，使用这些命令“最后”Einstein会转到新行。

Answer 1

为了给等宽文本连字，请加载不带\hyphenchar\font=-1; 的字体。为了允许在第一个单词中使用连字，请修改末尾的\@idxitem添加。\hspace{0pt}\ignorespaces
