Thanks Stephan and Phil for your valuable inputs.Yes with the new API it
seems to be rendering the lines which previously were being rendered as
'?'.However the bullets in the text are still being rendered as ? and if the
text contains some spaces marked by "grey areas" still render as '?' as i
had mentioned earlier. Any ideas on it?
Thanks again guys for ur suggestions!! :)
Regards,
Karl
