The Spesmilo Sign at U+20B7 is a currency symbol created for the spesmilo, a proposed international monetary unit associated with the Esperanto movement. It sits in the Currency Symbols block and represents a historical or planned currency sign rather than a currency in everyday circulation. Its real-world appearances are mostly in Esperanto-related material, numismatic references, Unicode charts, and discussions of constructed-language history. The spesmilo was promoted in the early 20th century for international payments among Esperantists, so the sign may be seen in archival price lists, membership records, or modern articles quoting that system. Today it is chiefly useful when transcribing historical documents accurately or cataloging currency symbols. It is not used for normal banking, exchange rates, or contemporary retail pricing, and many readers will recognize it only from specialist currency-symbol lists.
