ABC Stefan is a digitization of the artist Stefan Marx's handwriting, complete with lightning bolt-like swashes and a mistake function for crossing out errors. It's available in three subfamilies — Simple, Bubble, and Bubble Tight — and also contains an emoji pack of standard Apple icons rendered in Stefan's hand. Stefan has drawn four versions of every letter for ABC Stefan — and also four versions of every punctuation mark, symbol, and figure. A randomizer function built straight into the font software randomly displays different versions of letters as text is typed, creating subtle inconsistencies just like real handwriting.
