[AUCTeX] Fwd: Does preview of auctex support xetex now ?

[waterloo]

This is my latex file .  I can use xelatex to compile it to pdf . But I can not preview math environment in it .

\documentclass[11pt]{article}
\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\setmainfont[Mapping=tex-text]{LiHei Pro}
\begin{document}
kjhkljh
\XeTeX $\int$
\[\int\sum\] 
\end{document}

When I preview $\int$ in xelatex environment, I get the below error :

> gs -dOutputFile\=\(_region_.prv/tmp17941MEi/pr1-1.png\) -q -dSAFER -dNOPAUSE -DNOPLATFONTS -dPrinted -dTextAlphaBits\=4 -dGraphicsAlphaBits\=4 -sDEVICE\=png16m -r145.534x145.407
