SignWriting

@sutton-signwriting/font-db is a javascript package for node that generates SVG and PNG images for individual symbols, complete signs, and structured text. The package covers the entire set of the International SignWritnig Alphabet 2010 (ISWA 2010).

This package supports both Formal SignWriting in ASCII (FSW) and SignWriting in Unicode (SWU) character sets, along with the style string. See draft-slevinski-formal-signwriting for detailed specification.
