If you have Windows 2000/XP operating system in your computer, You can read Tamil Unicode websites easily. For others, please follow these instructions.
1. You should have Netscape 6, Internet Explorer 5 or above versions.
2. Some users of Windows 98/NT/ME/2000 Windows NT may find that even with a Tamil Unicode font installed and the browser correctly set to View > Encoding > Unicode, some of the Tamil letters are incorrectly displayed.
This may be due to the earlier version of usp10.dll used in these operating systems. To correct this, it may be necessary to update the usp10.dll file in Windows.
To do this,
i. Download the latest version of the usp10.dll file. You may download the file from the Microsoft site here. Save the downloaded .exe file. Double click on the file. Give a temporary folder address - the program will extract a few files into the folder - of these 'usp.zip' is the one you will need. Discard the other files. Unzip usp.zip. It will give two files viz: usp10.dll and readme.txt
ii. Go to the Windows folder and find the file named usp10.dll (usually in the System and/or System32 ). Rename the file to a different name say usp10.old .
iii. Place the newly downloaded usp10.dll file in the same folder.
iv. Restart the computer. Now you can see Unicode websites.
