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+20B4 prohibits a line break after it, if it is followed by a number.
The Wikipedia has the following information about this codepoint:
The hryvnia sign (₴) is a currency symbol, used for the Ukrainian hryvnia currency since 2004.
In 2004, when the National Bank of Ukraine approved the ₴ currency symbol for the hryvnia, it was also stated that the symbol could be written either before (₴500) or after (500 ₴) the denomination. The most recent Ukrainian orthography rules of 2019 do not regulate this usage.
