Cifrão

Cifrão on the reverse of a 2.50 Portuguese escudo coin

The cifrão (Portuguese pronunciation: [siˈfɾɐ̃w̃]) or cifrano^{[citation needed]} is a currency sign similar to the dollar sign ($) but always written with two vertical lines: $\mathrm{S}\!\!\!\Vert$. It is the official sign of the Cape Verdean escudo (ISO 4217: CVE) and a common unofficial^{[citation needed]} 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.^[1]

In Portuguese and Cape Verdean usage, the cifrão is placed as a decimal point between the escudo and centavo values (e.g., $2\mathrm{S}\!\!\!\Vert50$).^[2]

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. The Mac OS X supplies the following fonts containing distinct cifrão signs:^{[citation needed]} regular-weight Baskerville, Big Caslon, Bodoni MT, Brush Script MT, Garamond, STFangsong, STKaiti, and STSong. In LaTeX, with the textcomp package installed, the cifrão ($\mathrm{S}\!\!\!\Vert$) can be input using the command \textdollaroldstyle.

Because of the current difficulty supporting the character, $ is frequently employed in its place even for official purposes.^[3][4]

Other uses

In Mexico, it was used for dollars, to distinguish from local mexican currency which used the peso sign. However, the present convention is to use also the peso symbol for dollars, and specify USD (United States Dollars) after the currency is stated.
