I'm happy to announce a new feature for Gmail that lets you type email in Indian languages. If you're in India, this feature is enabled by default. If not, you'll need to turn it on in the "Language" section under Settings. Once enabled, just click the Indian languages icon and type words in the way they sound in English -- Gmail will automatically convert them to their Indian language equivalent.
For example, if you have Hindi selected, "namaste" will transliterate to "नमस्ते." Similarly, "vanakkam" in Tamil will become "வணக்கம்." We currently support five Indian languages - Hindi, Tamil, Telugu, Kannada, and Malayalam, and businesses and schools using Google Apps should see this in the coming weeks.
