The launch of a new feature in Gmail that makes it easy to type email in Indian languages.
When you compose a new mail in Gmail, you should now see an icon with an Indian character, as the screenshot below shows. This feature is enabled by default for Gmail users in India. If you do not see this function enabled by default, you will need to go the "Settings" page and enable this option in the "Language" section.
When you click the Indian languages icon, you can type words the way they sound in English and Gmail will automatically convert the word to its Indian local language equivalent. For example, if a Malayalam speaker types "Web Designer Kochi, Kerala" we will transliterate this to "വെബ് ഡിസൈനര് കൊച്ചി, കേരള." They currently support five Indian languages -- Hindi, Tamil, Telugu, Kannada and Malayalam -- and you can select the language of your choice from the drop-down list next to the icon.
