TTC: Collection of Two Variable Fonts
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.

Testing contract
Expected to pass- Scenario
- Open face 0 and face 1 by index and read fvar from each.
- Expected result
- Face 0 reports a wght axis and face 1 a wdth axis; instancing either one works without disturbing the other, and neither inherits the other's variation tables.
What is a .ttc file?
A TrueType Collection (.ttc) is a single file that bundles several related fonts, sharing common tables (like glyph outlines) to save space. It is used to ship font families or CJK fonts with many variants in one file. A font index selects which face inside the collection to use.
How to use this file
Use an example .ttc to test collection-aware font loaders, font-index selection, and tools that split a collection back into individual TTF/OTF files.
How to use this file for testing
“TTC: Collection of Two Variable Fonts” is a deterministic Testaroo 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.

- ttfTTF, Intentionally Corrupt: Wrong glyf Table-Directory ChecksumAn 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.
- ttfTTF, Intentionally Corrupt: Wrong head.checkSumAdjustmentAn 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.
- ttfTTF, Vertical Metrics: hhea, typo and win All AgreeThe 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.
- ttfTTF, Vertical Metrics: hhea, typo and win All DisagreeThe 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.
- 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.
