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+20B3 prohibits a line break after it, if it is followed by a number.
The CLDR project calls this character “austral” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: ARA, currency.
The Wikipedia has the following information about this codepoint:
The austral was the currency of Argentina between June 15, 1985, and December 31, 1991. It was divided into 100 centavos. The symbol was an uppercase A with an extra horizontal line, (₳). This symbol appeared on all coins issued in this currency (including centavos), to distinguish them from earlier currencies.
