In Web today there are plethora of Encoding used for Tamil including TAB/TAM (Tamilnadu
Govt. standard), TSCII (popular 8bit), TUNE and more. For each of these sites you
need to download and install respective fonts, definitely a pain. Recently I found
this Firefox Addon that
aims to solve this problem. After downloading and installing this addon "Adhiyan"
- press Alt-2 (for TSCII), Alt-5 (for TAB) and it changes the text in the page to
Unicode. So without installing the respective fonts, you can read all the text in
Unicode. Since it finds and replaces characters in the webpage, not all pages come
out correctly. But still a very handy utility.
