U+2E40 "⹀" Double Hyphen Unicode Character
Unicode Version 17.0
⹀
U+2E40 "⹀" Double Hyphen is a punctuation mark used primarily in historical and scholarly texts to represent a longer break or connection than a standard hyphen but less than a true dash, often appearing in older writing systems or as a specialized editorial symbol. It was encoded in Unicode 6.1.0 for use in scripts where two separate hyphen marks are required to be represented as a single glyph, such as in some dictionaries or linguistic notation, and it visually differs from a single hyphen by its doubled, slightly spaced form.
