我正在尝试使用包编写一些阿拉伯语 arabi。代码如下：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[LAE]{fontenc}
\usepackage[arabic]{babel}
\begin{document}
\selectlanguage{arabic}
مرحبا
\end{document}
我得到一张空白页，页面底部只有阿拉伯数字 1。
我的操作系统是 macOS Sierra，我使用 MikTex 的 xelatex。
输出：
This is XeTeX, Version 3.14159265-2.6-0.99998 (MiKTeX 2.9.6500)

由于您使用 XeTeX 进行编译，请不要加载fontenc或inputenc。您想使用。您可能想要fontspec而不是。babelpolyglossia
这是一个非常简单的例子。您需要指定系统上可用的合适字体。在我的系统上，Noto Naskh Arabic 支持阿拉伯语。
\documentclass{article}
\usepackage{polyglossia}
\setmainlanguage{arabic}
\newfontfamily\arabicfont[Script=Arabic]{Noto Naskh Arabic}
\begin{document}
مرحبا
\end{document}
