我有 3 个问题：
- 为什么以下代码（见下文）在 XeLaTeX 和 PDFLaTeX 中产生的结果不同？
- 哪一个是不正确的？（我猜测 XeLaTeX 的输出是不正确的。）
- 我怎样才能使不正确的输出变为正确的输出？
以下是比较结果（首先是 PDFLaTeX，其次是 XeLaTeX）：
\documentclass[]{beamer}
\mode<presentation>{\usetheme{Madrid}}
\hypersetup{pdfpagemode=UseNone}
\title[Short Title]{The Longer Title}
\author{Author}

答案1
假设您正在使用 pdfTeX 的直接 PDF 输出模式，那么您会看到这里有不同的特殊内容等等。因此，很难说一个结果是“正确的”，另一个结果是“错误的”，更确切地说，预计两者不会完全相同。选择一种编译路线并坚持下去！
