在TEX 和 LATEX 免费数学字体调查是 Latex 中协调字体的很好例子。
例如考虑以下文本片段CM 明亮：
和pdfLatex只需使用就足够了\usepackage{cmbright}，但我很难在luaLatex。这看起来要复杂得多。
经过几个小时的尝试和阅读字体规范文档我即将回到pdfLatex。
你能指导我如何使用CM 明亮在 luaLatex 中？
在 luaLatex 中设置新字体系列（包括数学）的一般方法是什么？
文档中以某种方式进行了解释，但很抱歉，LaTeX 人员并不是编写全面文档方面的佼佼者。
以下是 MWE：
前言：
\documentclass[a4paper]{article}
\usepackage{unicode-math}
\usepackage{amsmath}
\usepackage{fontspec} % lualatex font engine
\setmainfont[Numbers = Uppercase,
Ligatures = TeX,
BoldFont = CMU Bright SemiBold,
ItalicFont = CMU Bright Oblique,
]{CMU Bright Roman}
文档：
\begin{document}
\section{Let's try!}
\textbf{Theorem 1 (Residue Theorem).}
Let $f$ be analytic in the region $G$ except for the isolated singularities $a_1,a_2,\ldots,a_m$. If $\gamma$ is a closed rectifiable curve in $G$ which does not pass through any of the points $a_k$ and if $\gamma\approx 0$ in $G$ then
\[
\frac{1}{2\pi i}\int_\gamma f = \sum_{k=1}^m n(\gamma;a_k) \text{Res}(f;a_k).
\]
\textbf{Theorem 2 (Maximum Modulus).}
\emph{Let $G$ be a bounded open set in $\mathbb{C}$ and suppose that $f$ is a continuous function on $G^-$ which is analytic in $G$. Then}
\[
\max\{|f(z)|:z\in G^-\}=\max \{|f(z)|:z\in \partial G \}.

生产：
因此，文本似乎正确，但数学不正确。在过去几个小时的折腾中，我曾经算对了数学，但标题是错误的。我不记得我是怎么做到的，但我认为这并不重要。
答案1
unicode-math只有当您还拥有一个合理的“unicode math”字体并希望将其用作基础数学字体时才有意义。没有“cm bright math”（无衬线数学字体很稀疏......）。因此，最好以非 unicode 方式进行数学设置：
\documentclass[a4paper,12pt]{article}
\usepackage{cmbright}
\usepackage{amsmath,amssymb}
\usepackage{fontspec} % lualatex font engine
\setmainfont[Numbers = Uppercase,
Ligatures = TeX,
BoldFont = CMU Bright SemiBold,
ItalicFont = CMU Bright Oblique,
]{CMU Bright Roman}
