Gmail just added a new feature to send emails in Indian languages. Go to the language options in the settings page to enable this. Once you do this you will see a “अ” icon. Click it and start typing phonetically. So if you type “Vasanth” it is automatically translated to “வசந்த்” in Tamil or “वसंत” in Hindi. Cool!
There are also correction options available. You can also mix multiple Indian languages in the same email.
