TTF — Variable Font with a Non-Linear avar Mapping
The same three masters as the plain wght variable font, plus an avar table that warps the axis so most of the weight change happens in the first third of the slider. Diff it against its no-avar twin: identical outlines, different rendering at every intermediate value. Original typeface, free to use.

Testing contract
Reference control- Scenario
- Render both this font and its no-avar twin at wght 640 and compare.
- Expected result
- The avar font renders noticeably heavier at the same user coordinate, because avar maps 0.375 of the normalised range to 0.6875; at 300, 400 and 900 the two are identical.
What is a .ttf file?
TTF (TrueType Font) is a scalable outline font format developed by Apple and Microsoft that uses quadratic Bezier curves and includes hinting for sharp rendering at small sizes. It stores glyph outlines, metrics, and character mappings in a single file. It is one of the most widely supported desktop and web font formats.
How to use this file
Use an example TTF to test font parsers, glyph and metric extraction, text-rendering pipelines, and converters that produce web font formats like WOFF.
How to use this file for testing
“TTF — Variable Font with a Non-Linear avar Mapping” is a deterministic Novus Examples fixture for Conversion testing, Metadata testing. 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.

- ttcTTC — Collection of Two Variable FontsA collection whose members are themselves variable fonts, each with its own axis, fvar, gvar and STAT. The case that breaks loaders which handle collections or variations but never both at once. Original typeface, free to use.
- ttcTTC — Three-Face Collection with Shared TablesA TrueType Collection holding three faces of one family with identical tables stored once and referenced by offset from each face's table directory. For testing face-index selection, collection-aware loaders, and extractors that must not assume each face owns its tables. 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, Apple sbix PNG StrikeAn sbix colour font — Apple's embedded-bitmap format, one 128 ppem PNG strike per icon glyph, with vector glyf outlines kept underneath for renderers that ignore sbix. For testing bitmap-strike extraction and the strike-versus-outline decision. Original typeface, free to use.
- ttfTTF — Colour Font, CBDT/CBLC PNG StrikeA CBDT/CBLC colour font — the embedded-bitmap format Android and Chrome use for colour emoji, here with a 64 ppem 32-bit strike in image format 17. For testing bitmap-strike parsers and the CBDT-versus-sbix branch in a colour-font pipeline. Original typeface, free to use.
- ttfTTF — Composite Glyphs (accents built from components)Four precomposed accented letters built the way real fonts build them — as composite glyphs referencing a base letter and a combining mark with a translation. For testing component resolution, nested-glyph handling, and subsetters that must keep a component's base glyph alive. Original typeface, free to use.
