我做错什么了？似乎缺少连字符。
这是一个最小的可重现示例：
\documentclass[a5paper,12pt]{article}
\usepackage{xltxtra}
\usepackage{xunicode}
\usepackage{polyglossia}
\setdefaultlanguage{french}
\begin{document}
Couvert de sa cape blanche à doublure rouge sang,
marchant d’une démarche traînante de cavalier, tôt un matin du quatorze du mois
printanier de nisan, sous le portique couvert qui séparait les deux ailes
\end{document}
这就是我的呈现方式：
xelatex 1.tex
输出如下xelatex：

最有可能的是，原始来源（但不是此处发布的文件）有不间断空格 U+00A0 而不是空格。
