Better-Engineered Font Formats; Part 1. Boring Expansion
Browse cluster: Font design, tooling, and parsing →The boring-expansion-spec project proposes enhancements to the Open Font Format standard, specifically addressing limitations in how fonts handle glyphs, curves, and variations. The project aims to break the 65,000-glyph limit in single font files, add support for cubic curves in glyph outlines, enable variable components, and enhance core variation capabilities through improved axis mapping and sparse variation data storage. The work consists of formal proposals and draft specifications submitted to ISO's MPEG working group on Open Font Format, with documents authored in LibreOffice and Microsoft Word and distributed in multiple formats including markdown, PDF, and ODT.
