TTF — Subset with Layout Features Dropped
The same probe-character subset with every OpenType feature stripped — what many web-font pipelines produce by default. GSUB and GPOS survive as empty shells, so a tool that merely checks whether the tables exist reports the font as fully featured while nothing ligates, kerns, or turns into small caps. Original typeface, free to use.

Testing contract
Reference control- Scenario
- Measure the string 'AVAILABILITY' in both twins at the same size.
- Expected result
- This font renders it unkerned and is 7536 bytes smaller; the twin kerns it, neither font is missing a glyph, and both still report a GSUB and a GPOS table.
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 — Subset with Layout Features Dropped” is a deterministic Novus Examples fixture for Conversion testing, Performance testing, Error handling. 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 — 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.
- ttcTTC — The Same Three Faces with Tables UnsharedThe 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.
- 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 — Correct Checksums (integrity reference)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 complaining about. Original typeface, free to use.
- 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.
