The fonts category carries one small demonstration typeface, generated from scratch with fontTools and exported across the four common font formats. The same glyph set ships as TrueType (TTF), OpenType/CFF (OTF), and the two web-optimised wrappers WOFF and WOFF2, so you can convert one and diff against the others or point a font loader at each container. Every file has fixed creation timestamps for reproducibility and documents its glyph coverage. The typeface is original and free to use, a fixture for testing font conversion, subsetting, and @font-face loading rather than a display face.

Results start with a representative from each related test family. Use a card’s variant menu or the filters below to reach a specific format, profile, or failure case; every sample retains its own detail page and download.
No, it's one small demonstration typeface generated from scratch with fontTools, original and free to use. It's a fixture for testing conversion and loading, not a display face.
The same glyph set as TrueType (TTF), OpenType/CFF (OTF), and the two web wrappers WOFF and WOFF2, so you can convert one and diff the others. Additional samples cover a monospace face, an icon font, a bitmap BDF, and a TrueType Collection (TTC).
Testing font conversion, subsetting, and @font-face loading. Every file has fixed creation timestamps for reproducibility and documents its glyph coverage.
Start with one example from each use-case group, then continue through its other test families. Choose a use case, search, or filter to find a specific profile; a card’s variant menu contains its related samples.

Bitmap
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.
Collection
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 t
Color
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
Icon
An icon font with six simple pictographs (star, heart, check, arrow, circle, square) mapped to the Private Use Area (U+E000–U+E005), with the glyph map documented in the spec. A fixture for testing icon-font loading, @fo
Integrity
The clean control for the checksum pair: a small, valid font whose head.checkSumAdjustment and every table-directory checksum are correct. Diff it against its damaged twin to see exactly which four bytes a validator is c
Layout Features
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 pa
Metrics
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 entire
Mono
A fixed-width (monospace) demonstration typeface where every glyph shares the same advance width: a fixture for testing monospace detection, code-editor rendering, and column alignment. Original and free to use.
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.
Sans Sample
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, su
Subset
The complete face the rest of the subset set is cut from: the whole glyph repertoire with ligatures, kerning, contextual alternates, small caps, stylistic sets, figures, fractions, marks and localised forms intact. Measu
Variable
A tiny demonstration font declaring a Weight (wght) fvar axis, for VF-aware loaders and specimen tools.
Variable Axes
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
Variable Instances
A real static instance cut from the wght variable font at 900. Outlines interpolated once and baked, fvar and gvar stripped, usWeightClass set to match. For testing static-versus-variable fallback paths and family/style
Web Compression
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 ty
Collection
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.
Variable
Demonstration variable-font SAMPLE with a wght axis for variable-font loaders.
Variable
Variable-font instance note SAMPLE #1.
