My friend would like to be able to display Tamil pages on an eMac 1.42 GHz running Leopard, so his mom can use the computer when the PC is down because of viruses.

Currently, all pages show up as empty boxes or boxes with a squiggly line inside of it. I tried all browsers, even the anemic Internet Explorer.

Here is a page in Tamil: http://ta.wikipedia.org/

The "additional fonts" are installed with the Leopard installation. Still, everything shows as boxes.
