Snow leopard (Mac OS X 10.6), Punjabi and Unicode 5.1

Newly available Mac Snow Leopard, which suppose
to be supporting Unicode 5.1 standard.
After upgrading from Mac OS X 10.5 (leopard) to
Mac OS X 10.6 (Snow Leopard), Finally
I got that it is not supporting Punjabi (Gurmukhi) with
Unicode 5.1 standard.

Please use This Test Page to test Gurmukhi Unicode,
where you will find that following characters are missing
from fonts.
0A01
0A03
0A33 //This Test case working on 1 Mac machine, not on mine
0A51
0A75

Need to test other Indian Languages, not sure about
Apple's statement about Unicode 5.1 support whehter
it is about Indic language or not.

For Gurmukhi, need bug, going to file after confirming
with more mac users.
