Indic special characters on XeLaTeX

Question

I am using XeLaTeX (XeTeX, Version 3.1415926-2.4-0.9998 on TeX Live 2012/W32TeX). There are some special Indic unicode characters which XeLaTeX does not seem to support. I am trying to produce character र्ऋ - which is character no. 1011 on this page - http://ccat.sas.upenn.edu/plc/tamilweb/trans/unicodehindi.html - it is combination of three unicode symbols hexadecimal codes are 0930, 094d, 090b. In Word, I can type using 0930 Alt-X 094d Alt-X 090b Alt-X which produces र्ऋ correctly. Then I can copy paste and all applications like notepad, Firefox, get it right. But in XeLaTeX it does not work. The following compiles successfully, but renders र्ऋ as "र् ऋ" (without a space in between). The hex chars also do not work.

\documentclass[14pt]{article}
\usepackage{polyglossia}
\usepackage{fontspec}
\setmainfont[Script=Devanagari]{Arial Unicode MS}
\begin{document}
र्ऋ \char"0930\char"094d\char"090b
\end{document}

Thanks in advance.

Update on 2012-12-15: This works fine with Sanskrit 2003 font. I am yet to find a solution for Arial Unicode MS though.

\documentclass[14pt]{article}
\usepackage{polyglossia}
\usepackage{fontspec}
\setmainfont[Script=Devanagari]{Sanskrit 2003}
\begin{document}
रृ  
\end{document}

Using this currently - works with my font. The question may be considered solved for now.
