Gemma
Mota Italic · Rob Keller · 2012

A five-weight, three-width geometric sans by Rob Keller with unusually broad language support, 'rotalic' alternatives to italic, and an extensive OpenType feature set including weight-responsive dingbats.
About
Released in 2012, the family spans 45 fonts across five weights and three widths, with the x-height shifting vertically as the width changes horizontally. Instead of conventional cursive italics, Gemma offers two sets of 'rotalic' styles for emphasis, and every font includes the Futurama Alienese script alongside Latin, Greek and Cyrillic. The OpenType implementation is notably deep, covering small caps, 16 figure styles, contextual alternates, German-aware ligature handling and 18 stylistic sets.
Classification
Gemma is a geometric-leaning sans-serif with playful proportions and multiple widths, positioned as a versatile display and text family rather than a strict neutral grotesque.
