Do you want to be able to read Assamese, Bengali, Gujarati, Kannada, Malayalam, Marathi, Oriya, Punjabi, Tamil &  Telugu on your Android device?. It is possible on Android 4.0.3+ . IceCream Sandwich ( Android 4) enabled Indic font rendering on your apps and browser.
As a continuation to Malayalam Font for Android ICS & Gingerbread , I’ve implemented the solution for almost all Indic Languages. The complex letters based on combination of sounds may not render properly but you will be able to read the scripts nevertheless.
Languages supported till now are:

• Assamese
• Bengali
• Devanagari / Hindi
• Gujarati
• Kannada
• Malayalam
• Marathi
• Oriya
• Punjabi
• Tamil
• Telugu

Steps:

1. Copy the right ZIP file for your phone/ROM  to your SD card.
2. Reboot your phone to recovery mode . You will need  ClockWorkMod Recovery for this tweak to work.
3. Choose update from sdcard. Locate the ZIP file and update it.
4. Reboot.

Now , You will be able to read the scripts in any of the above language in almost all the apps without any hacks.
