This character is a Currency Symbol and is mainly used in the Tamil script. The character is also known as rupai.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as end of a European number, e.g., a currency symbol, from left to right. When changing direction it is not mirrored. U+0BF9 prohibits a line break after it, if it is followed by a number.
The Wikipedia has the following information about this codepoint:
The rupee sign "₨" is a currency sign used to represent the monetary unit of account in Pakistan, Sri Lanka, Nepal, Mauritius, Seychelles, and formerly in India. It resembles, and is often written as, the Latin character sequence "Rs", of which (as a single character) it is an orthographic ligature.
It is common to find a punctuation mark between the rupee symbol and the digits denoting the amount, for example "Re: 1" (for one unit), or "Rs. 140" (for more than one rupee).
On 15 July 2010, India introduced a new currency symbol, the Indian rupee sign, ₹. This sign is a combination of the Devanagari letter र (ra) and the Latin capital letter R without its vertical bar (similar to the R rotunda).
