[XeTeX] Arial unicode with slanting feature

[Nannilam, Baskaran (TNQSoftware)]

Hi

I am using some text in "Arial Unicode MS". I need slant (italic) a word 
which is in Arial Unicode font.

I tried below command, it is working fine
\font\slantfont="Arial Unicode MS:slant=0.2"

But I could not know how to give the font feature in

\newfontfamily\slantfont[..]{Arial Unicode MS}

Kindly suggest and guide me

Thanks and Regards
Baskar
