The cifrão (Portuguese pronunciation: [siˈfɾɐ̃w̃] (listen)) is a currency sign similar to the dollar sign ($) but always written with two vertical lines: . It is the most popular currency symbol in the Northern Hemisphere, as well as the symbol of the former Portuguese currency and is the official sign of the Cape Verdean escudo (ISO 4217: CVE).
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$50). The name originates in the Arabic cifr.
Support for the symbol varies. As of 2019[update], the Unicode standard considers the distinction between one- and two-bar dollar signs a stylistic distinction between fonts, and has no separate code point for the cifrão. The symbol is not in the October 2019 'pipeline', but appears to be under active consideration.
The following fonts display a double-bar dollar sign for code point 0024: regular-weight Baskerville, Big Caslon, Bodoni MT, Bradley Hand ITC, Brush Script MT, Garamond, STFangsong, STKaiti, and STSong ($).
In LaTeX, with the textcomp package installed, the cifrão () can be input using the command
However, because of font substitution and the lack of a dedicated code point, the author of an electronic document who uses one of these fonts intending to represent a Cifrão cannot be sure that every reader will see a double-bar glyph rather than the single barred version.
Because of the continued lack of support in Unicode, a single bar dollar sign is frequently employed in its place even for official purposes. Where there is any risk of misunderstanding, the ISO 4217 three letter acronym is used.
In Mexico, Colombia, Argentina and Chile, it was used for dollars, to distinguish from local currency which used the peso sign. However, the present convention in these countries is to specify USD (United States dollars) after the value.
