Android OS for mobile phones is yet to have inbuilt support for Tamil Unicode fonts.
However there are some free apps that support to read and write Tamil Unicode font in Android apps and browsers:
* Tamil Visai – To type Tamil in any Android app using transliteration, Tamil99 keyboard. Using this you can publish in Unicode Tamil font in websites. You can also send Tamil SMSes to other phones supporting Tamil display.
* SETT browser – To display Tamil Unicode text properly.
* Opera Mini browser can display Tamil Websites as bitmap images. Select YES for “Use BitMap fonts for complex scripts” in the settings.
But still, there is no inbuilt support yet. So, you cannot see Unicode Tamil text in all applications. You can’t read Tamil SMSes and there is no Tamil interface yet. Since Android is a open source software and Indic market can’t be ignored for long, we can hope to see inbuilt Tamil support soon in Android.
If you are power user, you can root your android phone and install Tamil Unicode font provided by Krishnan.
If you are an application developer, you can use TSCII fonts to display Tamil letters in your app.
The latest news is that Samsung Ace mobile phone gives native support for Tamil in Android OS. ( Tip: @mayooresan )
