A hand-written 5×7 BDF bitmap font covering the digits, a colon, and space: the classic X11 bitmap-font format, in plain text. A fixture for testing BDF parsers, bitmap-font converters, and retro/embedded rendering.
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.
COLR 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.
The Novus Sans Sample demonstration typeface as OpenType/CFF outlines: one member of a TTF/OTF/WOFF/WOFF2 conversion set built from scratch with fontTools. Original and free to use; a fixture for testing font loading, subsetting, and conversion.
A 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.
The 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.
A 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.
The same three faces in a collection that stores every table separately, so each face's directory points at its own copy. Identical rendering, a bigger file: the reference that makes the shared-table saving measurable rather than assumed. Original typeface, free to use.
A 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.
A TrueType Collection (.ttc) bundling two fonts (the Novus Mono Sample and Novus Icons) in a single container file. A fixture for testing TTC parsing, font-index selection, and collection-aware loaders.
An intentionally corrupt font whose glyf table data is perfectly fine but whose recorded checksum in the table directory is wrong. The complement to the head fixture: this one catches tools that verify per-table checksums, and its glyphs still draw, so the damage is invisible without a real integrity check.
An intentionally corrupt font: four bytes of head.checkSumAdjustment overwritten with 0xDEADBEEF and nothing else touched. It still renders, because browsers and operating systems do not verify the field, which is precisely why this is a useful fixture for validators, signing tools, and font-integrity checks that claim they do.
The full face subset to U+0030-U+0039 (digits only): a numeric-display cut, the shape a dashboard font ends up. Layout features are kept, so lookups whose glyphs were removed are the ones you can watch disappear. Original typeface, free to use.
The full face subset to the 8 codepoints of the string NOVUS 07: the extreme case a headline-only web font gets cut down to. Layout features are kept, so lookups whose glyphs were removed are the ones you can watch disappear. Original typeface, free to use.
The full face subset to U+0020-U+007E (printable ASCII): the range a Latin-only page actually needs. Layout features are kept, so lookups whose glyphs were removed are the ones you can watch disappear. Original typeface, free to use.
The control case: all three vertical-metric families carry the same numbers, so every platform computes the same 1.0 em default line height. Measure this first, then measure its disagreeing twin: the difference is entirely the metrics. Original typeface, free to use.
The same outlines with all three vertical-metric families deliberately set to different sums: 1000, 1250 and 1400 units. The default line height a renderer produces tells you exactly which family it read, which is the fastest way to explain why one browser or one word processor lays your text out differently from the rest. Original typeface, free to use.
An aalt feature that aggregates every alternate reachable through the stylistic sets and the small-cap set, which is what a glyph-palette UI reads to offer 'other forms of this character'. For testing alternate-picker panels rather than automatic shaping. Original typeface, free to use.
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.
An 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.
A 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.
A 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.
A 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.
An OpenType-SVG colour font: one inline SVG document per icon glyph, each with its own gradient, plus glyf outlines for renderers with no SVG support. For testing the fourth colour-font path and how a rasteriser handles vector colour it has to parse rather than paint. Original typeface, free to use.
