I am surprised to see few websites where they have kept normal unicode font (tamil language). But while displaying the website it is seen not as a normal unicode font but it looks more attractive and stylish.
For example: http://dinakaran.com/News_Detail.asp?Nid=33281
How it is possible?
These are custom fonts loaded on the listed example via CSS. So, you have to use utf-8 encoding.
And configure your custom fonts via CSS and
@font-faceto get the same effect.
