Any link for a free tamil font for an Android application

I have an android app that displays content in tamil. I understand how I can display tamil fonts in my application by adding a font.

My problem is that the fonts that are used on the Internet do not display correctly in the Android application. So the questions are ...

• My content is stored in db format in UTF-8 format. So, if I show this on the client side, do you have any links for free tamil fonts that I can use in my application?
• I saw several links to TSCII fonts. If I want to use this in my application, should I store the contents also in TSCII encoding? Or Can I save the contents in UTF-8 and display using the TSCII font?
