Re: SMuFL Metadata for ligatures and alternates

Thanks, Daniel. Where do the human-readable names on the glyph tables in
the Specification section on the SMuFL site come from? The alternates and
ligatures on pages such as
https://w3c.github.io/smufl/gitbook/tables/time-signatures.html all have
human-readable descriptions.
