On July of 2010 the Indian government announced the new currency symbol for the Indian Rupee. The original Rupee symbol will still be used in various other countries. The Indian Ministry of IT has been working with the Unicode standards group to include this symbol in the Unicode table 6.0 and will announce further information on supporting the new symbol on keyboards soon.
The new Rupee symbol will be supported in Windows vista and later and Windows server 2008. You can find the update for Windows Vista, for Windows Server 2008, for Windows 7 and for Windows Server 2008 R2 here. This update adds support for the new currency symbol for the Indian Rupee. It also includes font support (called Rupee_Foradian.ttf), locale changes, keyboard support, English (India) keyboard support, and how to select the English (India) keyboard.
