[XeTeX] How to render this symbol in Xelatex

[A u]

Hi,
I am using Texworks as editor. Sanskrit 2003 font in Ubuntu.
I could render all alphabets except the attached image.

I produced this in windows using iTranslator software.

I followed these instruction to make devanagari input in Ubuntu.

I tried to add the symbol after this "sudo gedit
/usr/share/m17n/hi-itrans.min"
but that did not work, it adds a "*" but not the symbol.

Thanks for your help
