U+1D98C "𝦌" Signwriting Movement-Wallplane Curve Half-Circle Small Unicode Character

U+1D98C "𝦌" Signwriting Movement-Wallplane Curve Half-Circle Small is a symbol from the Sutton SignWriting script, which is designed to visually represent the movements and handshapes of signed languages in written form. This specific glyph denotes a small, half circle shaped movement that occurs against the wallplane, which is the vertical plane parallel to the signer’s body, and it appears in the SignWriting block of the Unicode standard. Its purpose is to enable precise transcription of nuanced hand and arm motions, such as a slight arc or curve, that are fundamental to accurately documenting the physical grammar of sign languages like American Sign Language through a standardized, non phonetic script.
