Now a days there are many online indic langauge unicode compliant news
papers available, i was used to to take some sample data from that pages
while my testing work,

for Devanagari Script, There is http://maharashtratimes.indiatimes.com/ is
good online new paper

bbc news provides for most of the script i think

i think if you can make any folder with anonymous access, say as a test data
people can put some test data there, as well corresponding pdf(windows
renderering sample), but we should be carefull that we want latest Uniscribe
with OT Specs 1.6
I guess windows only ships that uniscribe with Vista

also making a team for testing will be nice thing i.e


Testing Team:

Devanagari: Pravin S, .. .. ..
Bengali : .......
Gujarati :
Tamil :
Telugu :
Malayalam :
Oriya :
Kannada :
Gurumukhi (Punjabi) :
Sinhala :

also how to test will help lot some people :)

Thanks & Regards,
