OTF — CFF (Cubic) Outlines
The same design in CFF outlines: cubic Type 2 charstrings with no glyf and no loca. The half of the pair that catches code assuming every OpenType font is TrueType-flavoured. Original typeface, free to use.

Testing contract
Reference control- Scenario
- Convert this file to TrueType outlines and compare with the TTF twin.
- Expected result
- Shapes match within conversion tolerance; the table directory here shows CFF and no loca, and the file is 4868 bytes against the twin's 6336.
What is a .otf file?
OTF (OpenType Font) is a scalable font format built on the TrueType structure but able to carry PostScript/CFF cubic-Bezier outlines and advanced typographic features like ligatures and alternates. It supports large Unicode glyph sets and rich layout tables. It is a professional-grade format for desktop and web.
How to use this file
Use an example OTF to test OpenType parsing, advanced layout-feature handling, glyph extraction, and font-conversion or subsetting pipelines.
How to use this file for testing
“OTF — CFF (Cubic) Outlines” is a deterministic Novus Examples fixture for Conversion testing, Web assets. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: seed 20260807. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Font fixtures carry a small documented glyph set across the common wrappers. Test font loaders, subsetting, and @font-face; the specimen preview renders the glyphs the face actually maps.

- otfOTF — Colour Font, COLR Layers over CFF OutlinesCOLR and CPAL over CFF rather than glyf outlines. COLR is outline-agnostic by specification, but plenty of tooling assumes colour fonts are TrueType-flavoured — this is the file that finds out. Original typeface, free to use.
- otfOTF — Variable Font with CFF2 (cubic) OutlinesA variable font whose outlines are CFF2 rather than glyf, so the variation deltas live inside blended charstrings and there is no gvar table at all. The case that breaks tools which assume every variable font is TrueType-flavoured. Original typeface, free to use.
- otfOTF — Web Container Source, CFF (Type 2) OutlinesThe uncompressed CFF (Type 2) source for this container set. Every WOFF and WOFF2 file in the group is packed from exactly these bytes, so a compression comparison is measuring the container and nothing else. Original typeface, free to use.
- ttfTTF — Colour Font with Four Named CPAL Palettes (light/dark)A colour font carrying four CPAL palettes with name-table labels and palette-type flags, two of them marked usable with a light or a dark background. For testing palette pickers, the CSS font-palette property, and renderers that only ever read palette zero. Original typeface, free to use.
- ttfTTF — Colour Font, COLR v0 Layers with CPALA COLR version 0 colour font: three Private Use Area icons, each drawn as two layer glyphs that index CPAL palette entries, with ordinary monochrome glyf outlines underneath as the fallback. The baseline colour-font case that every modern browser supports. Original typeface, free to use.
- ttfTTF — Colour Font, COLR v1 Linear and Radial GradientsA COLR version 1 colour font built as a real paint graph: a linear gradient with pad extend, a radial gradient with reflect, a repeating three-stop gradient, and a solid paint with fractional alpha. For testing gradient support, extend-mode handling, and the v1-to-v0 fallback path. Original typeface, free to use.
