# xepersian and qtree incompatibility?

I am a linguist and want to display trees. I tried the the following code.

\documentclass{article}

\usepackage{xepersian}

\usepackage{qtree}

\begin{document}
\begin{latin}

\begin{figure}

\Tree
[.case nom gen dat acc ]

\end{figure}

\end{latin}

\end{document}


I called it with xelatex. This works without the xepersian package loaded but fails with the package loaded. With the package loaded, I just get the lines, but the words (case nom gen dat acc) are missing.

Make a bug report in github.com/vafa/xepersian/issues but I do not promise updating xepersian package unless there is some donations to the project. –  Vafa Nov 4 '12 at 11:29

switch to LM or another font:

\documentclass{article}
\usepackage{qtree}
\usepackage{xepersian}
\newfontface\LM{Latin Modern Roman}
\begin{document}
\begin{latin}
