Srijika: OpenType-Layout-Reusing Font Restyling for Nine Indic Scripts

Srijika restyles glyph outlines from template fonts with latent diffusion to produce 66 OpenType TTFs across nine Brahmic scripts while preserving shaping consistency.

Srijika produces installable OpenType fonts for nine Brahmic scripts, including Devanagari, Tamil, and Bengali, by restyling glyph outlines from shaping-complete template fonts rather than generating from scratch. It preserves the template's cmap, GSUB closure, and GPOS data under a documented metric policy, yielding 66 TTFs that all pass the OpenType Sanitizer with HarfBuzz and CoreText reproducing template glyph-ID sequences. A reference-conditioned latent diffusion model redraws glyphs in a style selected via Lipika, a retrieval index over roughly 650 open-license font families, with content gating and shaped-cluster verification. The report also contributes a negative-results catalogue and cautions that measured style movement depends on an internal embedding trained on held-out families.
