The cifrão (Portuguese pronunciation: [siˈfɾɐ̃w̃]) is a currency sign similar to the dollar sign ($) but always written with two vertical lines: . It is the official sign of the Cape Verdean escudo (ISO 4217: CVE) and a common sign of the Brazilian real (sign: R$; ISO: BRL).

It was formerly used by the Portuguese escudo (ISO: PTE) before its replacement by the euro and by the Portuguese Timor escudo (ISO: TPE) before its replacement by the Indonesian rupiah and the US dollar. In Portuguese and Cape Verdean usage, the cifrão is placed as a decimal point between the escudo and centavo values (e.g., 2$50). The name originates in the Arabic cifr.

Character support

Support for the symbol varies. The Unicode standard currently (2010) considers the distinction between one- and two-bar dollar signs a stylistic distinction between fonts and has no separate value for the cifrão. Mac OS X supplies the following fonts containing distinct cifrão signs: regular-weight Baskerville, Big Caslon, Bodoni MT, Brush Script MT, Garamond, STFangsong, STKaiti, and STSong ($). In LaTeX, with the textcomp package installed, the cifrão () can be input using the command \textdollaroldstyle.
