[XeTeX] wrong strikethrough?

[Pablo Rodríguez]

Hi there,

I'm not sure whether this have been recently asked, but I would like to 
strike through some words in red, being the text in black.

I'm using the following code:

\documentclass{article}
\usepackage{soul,xcolor}
\setstcolor{red}
\begin{document}
\st{overstriking?}
\end{document}

But the issue here is that the text is over the striking line and not 
vice versa (as I guess it should be).

Is there no way to fix this?

Thanks,


Pablo
