Creating searchable Tamil PDF is a long time dream for Tamil People.
For so many reasons like PDF standards, Unicode Issues with Tamil,
Issues with rendering engines, etc, we could not copy/paste any tamil
content from PDF files.

We have a issue for this here
https://github.com/KaniyamFoundation/ProjectIdeas/issues/78

Today morning, I was reading this issue and explored about PDF files.
Found a PDF/A standard. It promised to give Unicode support. Is it
means a PDF/A file in Tamil is searchable?

YES. YES. YES.

Tested this using Libreoffice Writer and yeah. It works. I can copy
the tamil text as it is and even do a search within the PDF.

Here is a demo video on this in Tamil.
