The rial (Persian: ریال ایران, romanized: riyâl-è Irân; sign: ریال ; abbreviation: Rl (singular) and Rls (plural) or IR in Latin; ISO code: IRR) is the official currency of Iran. There is no official symbol for the currency but the Iranian standard ISIRI 820 defined a symbol for use on typewriters (mentioning that it is an invention of the standards committee itself) and the two Iranian standards ISIRI 2900 and ISIRI 3342 define a character code to be used for it. The Unicode Standard has a compatibility character defined U+FDFC ﷼ RIAL SIGN. A proposal has been agreed to by the Iranian Parliament to drop four zeros, by replacing the rial with a new currency called the toman, the name of a previous Iranian currency, at the rate of 1 toman = 10,000 rials.[clarification needed] From Wikipedia
