U+1D990 "𝦐" Signwriting Movement-Wallplane Curve Three-Quarter Circle Small Unicode Character

U+1D990 "𝦐" Signwriting Movement-Wallplane Curve Three-Quarter Circle Small is a symbol from the SignWriting script, a system designed to visually represent sign languages in written form. This specific character denotes a small, three-quarter circular movement occurring on the wall plane, which is the imaginary vertical surface in front of the signer, often used to indicate paths or shapes traced by the hands. It falls within the Sutton SignWriting block of the Unicode standard, contributing to the script's ability to precisely encode the spatial and movement components of signed languages for linguistic documentation and communication.
