U+FE69 Small Dollar Sign

The Wikipedia has the following information about this codepoint:

The dollar sign, also known as the peso sign, is a currency symbol consisting of a capital ⟨S⟩ crossed with one or two vertical strokes ($ or depending on typeface), used to indicate the unit of various currencies around the world, including most currencies denominated "dollar" or "peso". The explicitly double-barred sign is called cifrão in the Portuguese language.

The sign is also used in several compound currency symbols, such as the Brazilian real (R$), the Nicaraguan córdoba (C$) and the United States dollar (US$): in local use, the nationality prefix is usually omitted. In countries that have other currency symbols, the US dollar is often assumed and the "US" prefix omitted.

The one- and two-stroke versions are often considered mere stylistic (typeface) variants, although in some places and epochs one of them may have been specifically assigned, by law or custom, to a specific currency. The Unicode computer encoding standard defines a single code for both.

In most English-speaking countries that use that symbol, it is placed to the left of the amount specified, e.g. "$1", read as "one dollar".
