一些好心人在我的一些问题中提到我的用法\usepackage{fontspec}是错误的。其中一位建议我使用\setmainfont[Scale=1.0, Ligatures={Common, Rare, TeX}]{Palatino Linotype}，但它不起作用，因为我需要写出很多带有不常见重音和符号的字母，例如\ae或\'{\"{u}}或{\~o}等等。
我所做的就是使用 Candara 来编写章节和部分/小节等，并使用 Palatino 之类的字体来编写核心文本。

如果您将测试文档缩减为更适合此站点的内容，那么您可以轻松地测试加载 palatino 克隆，例如 TeX Gyre Pagella。
\documentclass[oneside,twocolumn]{book}
\usepackage{fontspec}
\setmainfont{TeX Gyre Pagella} % Palatino clone
\begin{document}
\ae
\'{\"{u}}
