我正在用 XeLaTeX 和 制作一个使用藏文 Unicode 字体的文档fontspec。但是，文本显示不正确。上标和下标字母出现在基本字母旁边，而不是在它们上面或下面，而且 tsheg 的外观很奇怪。我怀疑这是由于使用了错误的字体，但我不知道该换成哪种字体。谢谢。
\documentclass[10pt]{article}
\usepackage{fontspec}
\begin{document}
\setmainfont{Arial Unicode MS}
བོད་ཡིག་འདི་ལ་དག་པར་ཡོང་གི་མ་རེད།
\end{document}
更新：下面是编译此代码的摘录：
\documentclass{article}
\usepackage{fontspec}
\begin{document}
\setmainfont{Kailasa}
བོད་ཡིག་འདི་ལ་དག་པར་ཡོང་གི་མ་རེད།
\end{document}
“Kailasa” 是我的系统上安装的藏文字体；无论我使用哪种藏文字体，结果都是一样的。以下是文字记录的结尾：

由于某种原因，它无法识别在文档代码中输入的字符或找不到字体，尽管我确定它已安装在我的系统上。

我在这里找到了两种用于排版藏文的免费字体：http://digitaltibetan.org/index.php/Tibetan_Fonts#Freely_available_Unicode_fonts。
以下是使用这些字体的示例：
\documentclass[10pt]{article}
\usepackage{fontspec}
\begin{document}
\setmainfont{DDC Uchen}
བོད་ཡིག་འདི་ལ་དག་པར་ཡོང་གི་མ་རེད།
\setmainfont{Jomolhari}
བོད་ཡིག་འདི་ལ་དག་པར་ཡོང་གི་མ་རེད།
\end{document}
输出：
