U+1D988 "𝦈" Signwriting Movement-Wallplane Curve Quarter Small Unicode Character

U+1D988 "𝦈" Signwriting Movement-Wallplane Curve Quarter Small is a specific symbol within the SignWriting script, which is designed to visually represent the hand movements and facial expressions of sign languages. This particular glyph denotes a small, curved movement that occurs in the wallplane, meaning the motion is parallel to the signer's torso or the frontal plane of the body. As a "quarter" curve, it indicates a subtle, short arcing path rather than a full or half circle, and its small size suggests the movement is executed with a limited range. This character is part of a comprehensive system used by linguists, educators, and deaf communities to transcribe sign language in a written form.
