The Wikipedia has the following information about this codepoint:
The Bangladeshi taka (Bengali: টাকা, sign: ৳, code: BDT, short form: Tk) is the currency of Bangladesh. In Unicode, it is encoded at U+09F3৳BENGALI RUPEE SIGN.
Issuance of bank notes ৳10 and larger is controlled by Bangladesh Bank, while the ৳2 and ৳5 banknotes are the responsibility of the ministry of finance. The banknotes of Tk. 2 and Tk.5 have mostly been replaced by coins while lower denomination coins (including all poysha coins) up to Tk. 1 have almost gone out of circulation due to inflation. The most commonly used symbol for the taka is "৳" and "Tk", used on receipts while purchasing goods and services. It is divided into 100 poysha, but poysha coins are no longer in circulation. The poysha is still used for accounting purposes (e.g., Tk 123,456.78 for 123,456 taka and 78 poysha).
On 8 May 2024, the central bank placed the taka in a crawling peg to the US dollar, with a rate of 117 takas per US dollar.
