更新： 這似乎與我的 mac/mac 設定上的 pdfreaders 有關。當我在 Windows 電腦上的閱讀器上閱讀相同的檔案時，內容確實顯示出來
我使用 Latex 中的“pdfcomment”套件來產生帶有註釋的 pdf 文件。突然間它停止工作：圖示仍然出現在 pdf 中，但評論文字沒有顯示。
- 編譯：Latex、LaTeX2e、pdfTeX (TexLive)；也可以使用 XeLatex
- 在 texshop 以及 texstudio 中嘗試過
- 在 mac 的 Preview 和 Skim 中查看了 pdf
例子：
\documentclass[11pt,american,english]{article}
\usepackage{lmodern}
\usepackage[latin9]{inputenc}
\usepackage{pdfcomment}
\makeatletter
\makeatother
\begin{document}
This will presumably lead to the maximum number of marriages given the information structure, and, in our model, the highest material welfare. However, people will also sometimes learn they were rejected, and feel a sting. \pdfcomment[icon=note]{testing a pdf comment} Introducing the CAE would give people a way to avoid this sting, by rejecting and remaining ignorant (perhaps particularly when they anticipate likely being rejected).
\end{document}

如果我將您的語言要求移至 babel，我可以毫無問題地看到評論
%\documentclass[11pt,american,english]{article}
\documentclass[11pt]{article}
\usepackage[english,USenglish]{babel}
\usepackage{lmodern}
\usepackage[latin9]{inputenc}
\usepackage{pdfcomment}
\makeatletter
\makeatother
\begin{document}
This will presumably lead to the maximum number of marriages given the information structure, and, in our model, the highest material welfare. However, people will also sometimes learn they were rejected, and feel a sting. \pdfcomment[icon=note]{testing a pdf comment} Introducing the CAE would give people a way to avoid this sting, by rejecting and remaining ignorant (perhaps particularly when they anticipate likely being rejected).
\end{document}
不過，我建議您考慮您的評論放在哪裡，因為這是我的結果
