[Tugindia] charactwer "sha" in tamil omega 1.0.2

[P. P. Narayanaswami]

In tamil-omega-1.0.2, the Keyboard Input for Yudit Table  does not 
include the tamil character "sha" (as in shashi, shankara).  However,
Unicode has the character "sha" in slot 0BB6.
Is there any way I can get "sha" working in Tamil omega, either by
inserting that character in Yudit, or by writing a line in the preamble 
to invoke that character? Ay help will be appreciated.
