U+1D813 "𝠓" Signwriting Hand-Fist Index Up Middle Hinged Unicode Character

U+1D813 "𝠓" Signwriting Hand-Fist Index Up Middle Hinged is a glyph from the Sutton SignWriting script, representing a specific handshape used in written sign languages where the hand forms a fist with the index finger extended upward and the middle finger bent or hinged at the knuckle. This character encodes a precise articulatory configuration, allowing signers to denote a variant of the common "pointing" handshape by visually specifying the unique positioning of the middle finger. It is part of the relatively large block dedicated to SignWriting in the Unicode Standard, which enables digital representation of sign language notation without relying on images or font-dependent symbols.
