This character is a Currency Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as end of a European number, e.g., a currency symbol, from left to right. When changing direction it is not mirrored. U+20A1 prohibits a line break after it, if it is followed by a number. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:
The colón (₡) refers to two Central American currencies:
the Costa Rican colón (CRC), used in Costa Rica since 1896
the Salvadoran colón (SVC), used in El Salvador from 1892 until 2001, when it was replaced by the American dollar
