我有以下最少的文档：

\setmainfont{Linux Libertine O} % does not work
\begin{document}

当我注释该setmainfont命令并使用 xelatex 编译文档时，就复制和粘贴而言，我得到了在 iPad 上表现良好的结果：当我点击一个单词时，这个单词被选中。注释后setmainfont，我得到一个文档，点击后会选择整个句子或短语。我能对此做些什么吗？我使用的是 texlive 2014，所有软件包都已更新。
以下是两张截图。第一张图显示了预期的行为：点击“可选”并且“可选”被选中。
带有 libertine 的文档已选择完整的句子，或者更确切地说是从行首到下一个点或“-”的区域：
也许这和空格的处理有关。我可以想象，iPad 上的选择软件无法识别空格，它只是认为完整的句子是一个没有空格的对象。
这些是创建的 PDF：
