币界网报道：Bitcoin's official Unicode symbol ₿ is celebrating its 8th anniversary. Unicode version 10.0.0 was released on June 20, 2017, adding 8,518 new characters, including the Bitcoin symbol ₿. The symbol was proposed by hardware hacker Ken Shirriff in 2015 and was supported by the Bitcoin Foundation and several early Bitcoin community members. The ₿ symbol design was inspired by the icon of Satoshi Nakamoto's original Bitcoin client and represents a full Bitcoin. Although Unicode has recognized the Bitcoin symbol, the International Organization for Standardization (ISO) has not yet included Bitcoin in its list of currency codes. The Bitcoin Foundation tried to apply for ISO approval, but was unsuccessful. The official recognition of the symbol marks an important milestone for Bitcoin as a digital currency.
