[XeTeX] Follow-up to previous mail about hyphenation

[Yannis Haralambous]

Here is my code:

\documentclass{article}
\usepackage{polyglossia,fontspec}
\setdefaultlanguage{arabic}
\newfontfamily{\arabicfont}[Script=Arabic,Extension=.ttf,Scale=1.2]{Amiri-Regular}
\textwidth1cm
\begin{document}
\large
\lefthyphenmin1
\righthyphenmin1

\end{document}

and the patterns I have loaded for Arabic are 

\catcode"200D=11
\lccode"200D="200D
\patterns{
^^^^200d1^^^^200d
}

I don't get any hyphenation at all. When I remove the ^^^^200d and try a pattern between Arabic characters it works just fine,
so it is not a problem inherent in Arabic script.
