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+20A0 prohibits a line break after it, if it is followed by a number.
The Wikipedia has the following information about this codepoint:
The European Currency Unit (French: Unité de compte européenne, Spanish: Unidad Monetaria Europea, German: Europäische Währungseinheit ; ⟨₠⟩, ECU, or XEU) was a unit of account used by the European Economic Community and composed of a basket of member country currencies. The ECU came in to operation on 13 March 1979 and was assigned the ISO 4217 code. The ECU replaced the European Unit of Account (EUA) at parity in 1979, and it was later replaced by the euro (EUR) at parity on 1 January 1999.
As a unit of account, the ECU was not a circulating currency and did not replace or override the value of the currency of EEC member countries. However, it was used to price some international financial transactions and capital transfers.
