The document describes the Sutton SignWriting Standard of 2017, which provides a stable standard for writing sign languages using a two-dimensional representation. It summarizes the history and principles of SignWriting, and outlines the current standards for Formal SignWriting in ASCII (FSW) and SignWriting in Unicode (SWU). The standard uses characters for naming signs and fonts for viewing signs rendered with spatial coordinates. It aims to be complete, universal, empowering and possible for all sign languages.
