Datatype is an OpenType variable font that turns simple text expressions into inline charts. No JavaScript, no images, no rendering library — just type the syntax and Datatype’s ligature substitution does the rest.
Recently some other participants in the type-design industry asked me to endorse a letter to the U.S. Copyright Office about copyright registrations for digital fonts. The impetus was a set of concerns arising from ongoing rejections of font-copyright registrations and a recent opinion in a case called Laatz v. Zazzle pertaining to the infringement of font copyrights.
