Noto Sans SignWriting

A highly unconventional Noto font providing digital rendering for SignWriting, the visual notation system used to transcribe signed languages.
About
Noto Sans SignWriting is unlike almost any other typeface in the Noto collection, as its glyphs represent body positions, hand shapes, and movements rather than alphabetic characters. It serves deaf communities, linguists, and educators who use SignWriting to document and communicate in sign languages. The font is an engineering and accessibility achievement, though its visual character is entirely dictated by the notation system it encodes.
Classification
An unusually complex Noto family member supporting SignWriting, a system for visually transcribing signed languages. The glyphs are highly pictographic and diagrammatic rather than conventional letterforms.
