以下样本的缩写 covington 部分不会在 pdf 中显示。
在我尝试不同的天城体字体之前它就是这样的。
请帮忙。

即使这个答案对于 OP 来说太晚了，但根据记录：你\glt在注释中缺少终止和强制命令：
\documentclass[12pt,oneside]{article}
\usepackage{fontspec} %xltxtra,xunicode}
%\usepackage{tipa}
%\usepackage{polyglossia}
%\usepackage{etoolbox}
%\usepackage{pdfsync}
\usepackage{covington}
\usepackage{cancel}
\usepackage[parfill]{parskip}
\font\I="Devanagari MT" at 14pt
\defaultfontfeatures{Mapping=tex-text}
\setmainfont[Mapping=tex-text]{Charis SIL}

或者，如果您使用引入的宏covington 2.0：
