等宽字体（打字机字体）不尊重边距

Question

我尝试在文档中使用打字机字体 (TXTT)，但它总是超出边距。我不知道这是正常的还是我的文档出了错。

下面是一个 MWE：

\documentclass[a4paper, 12pt]{memoir}

% Load packages
\usepackage[showframe]{geometry}
\usepackage[colorlinks = true, urlcolor = blue, linkcolor = black]{hyperref}
\usepackage{enumitem}
    \setlist{itemsep=0.05em}
\usepackage{xfrac}
\usepackage{booktabs}
\usepackage{tocloft}
\usepackage{lipsum}

% TXTT typewriter font
\renewcommand*\ttdefault{txtt}
\renewcommand*\familydefault{\ttdefault} %% Only if the base font of the document is to be typewriter style
\usepackage[T1]{fontenc}

% Formatting matters
\setlength\parskip{1em}
\setlength\parindent{0em}
\renewcommand\contentsname{} % the empty ToC name
\renewcommand{\labelitemii}{$\circ$}

% =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
\begin{document}

\lipsum

\end{document}

Answer 1

您可以自行加载字体定义文件，并将其修改为

1. 允许连字符，因此删除\hyphenchar\font=\m@ne；
2. 为每种字体定义一个可拉伸性；
3. 为每种字体定义一个可收缩性。

\documentclass[a4paper, 12pt]{memoir}

\usepackage[T1]{fontenc}
\usepackage{kantlipsum}

\newcommand{\fixfontdimens}{%
