Lualatex 允许直接加载字体，无需包和其他依赖项。
我发现的问题是，pdflatex 和旧样式的用法有很好的文档记录，而使用 fontspec 命令的 lualatex 的用法没有文档记录。对于大多数用户来说，这仍然是加载包的最佳方式，但这似乎并不存在。
以下是我为 pdflatex 编写的一些示例，我想知道正确的 lualatex 方法。旧代码只能与\usepackage[T1]{fontenc}
MWE 示例
\documentclass[]{scrbook}
\usepackage{amsmath}
\usepackage{esint}
%\usepackage{unicode-math} % works not with old font loading
%\usepackage{fontspec}
\usepackage[T1]{fontenc}
\usepackage{mathptmx} %% --- Times (incl math)
\usepackage[scaled=.90]{helvet} %% --- Helvetica (Arial)
\usepackage{courier} %% --- Courier
\begin{document}
\chapter*{Font Test}
The text on these pages demonstrates the appearance of the used fonts for serif, \textsf{sans serif}, math and \texttt{typewriter fonts}.

\subsection*{Green's theorem}
\begin{equation}
\underset{\mathcal{G}\quad}\iiint
\left[u\nabla^{2}v+\left(\nabla u,\nabla v\right)\right]\mathrm{d}^{3}V
=\underset{\mathcal{S}\quad}\oiint u\,\frac{\partial v}{\partial n}
\,\,\mathrm{d}^{2}A
\end{equation}

这里还有一些我正在寻找字体规范定义的其他字体代码组合
% lmodern with sans math
\usepackage{lmodern}

作为当前字体的替换，您可以尝试以下操作（取消注释要测试的字体集）：
\documentclass[a4paper,openany]{scrbook}
\usepackage{amsmath}
\usepackage{unicode-math}
% -> Times, Arial, Courier (licence issues ???)
\setmainfont{TeX Gyre Termes X}
\setsansfont{Arial}[Scale=MatchLowercase] % msttcorefonts on Debian
\setmonofont{Courier 10 Pitch}[Scale=MatchLowercase]
\setmathfont{Latin Modern Math}
% -> Times, Arial, Courier
%\setmainfont{TeX Gyre Termes X}
%\setsansfont{TeX Gyre Heros}[Scale=MatchLowercase]
%\setmonofont{TeX Gyre Cursor}[Scale=MatchLowercase]
%\setmathfont{TeX Gyre Termes Math}
% -> Palatino, Arial, Courier

您不能期望一对一地替换您的 Type1 字体。但是，已经有大量免费的 OpenType 文本/数学字体可供使用。
