文本超出右边距，使用 \texttt{}

Question

我之前问过这个问题，但它与其他问题相关联，并被视为已关闭。我检查了链接问题的答案，它们没有回答我的问题，所以我再试一次。以下文本开始一个段落。排版时，第二句中的单词“the”打破了右边距：

Graunt decided to pen a scientific paper to show to Petty. In 1662 he produced
a series of tables based on mortality records. His article was called \texttt{Natural and
Political Observations Mentioned in a Following Index, and Made Upon the
Bills of Mortality.}

我可能可以通过改写前面的文字来解决这个问题，但如果能理解为什么这种情况会在这里发生，而不是在文档的其他地方发生，那就更好了。

Answer 1

我可以以某种方式重现该问题：

\documentclass[12pt]{article}

\begin{document}

Graunt decided to pen a scientific paper to show to Petty. In 1662 he produced
a series of tables based on mortality records. His article was called
\texttt{Natural and Political Observations Mentioned in a Following Index,
and Made Upon the Bills of Mortality.}

\end{document}

关于打字机类型，您应该了解以下几点：

1. 它没有设置词间空间的灵活性；
2. 它不受连字符的限制；
3. 单词间距与字母宽度相同；
4. 它完全不适合这份工作。

第 4 个问题与其他三个问题无关，可以得到修复。

\documentclass[12pt]{article}

\newcommand{\opus}[1]{%
  \begingroup
    \spaceskip=\fontdimen2\font plus \fontdimen3\font minus \fontdimen4\font
    \xspaceskip=\fontdimen7\font\relax
    \ttfamily
    %\hyphenchar\font=`\-
    #1%
  \endgroup
}

\begin{document}

Graunt decided to pen a scientific paper to show to Petty. In 1662 he produced
a series of tables based on mortality records. His article was called
\opus{Natural and Political Observations Mentioned in a Following Index,
and Made Upon the Bills of Mortality.}

\end{document}

您可能决定取消注释该\hyphenchar行（但请注意，打字机类型的所有文本都可能会被连字符连接）。

然而，这并不能解决问题 4：结果非常糟糕。

将定义替换\opus为

\newcommand{\opus}[1]{\textit{#1}}

结果会看起来好得多：

现在您可以选择。
