TTF — Fractions (frac) with numr and dnom
A real frac implementation as a chaining contextual substitution: the slash becomes a fraction slash, the digit before it becomes a numerator and the digit after becomes a denominator, with numr and dnom also reachable on their own. Coverage is deliberately limited to single-digit fractions, which is stated in the specs so a test can assert the boundary. Original typeface, free to use.

Testing contract
Expected to pass- Scenario
- Shape '1/2 and 3/4' with frac enabled, then '15/16'.
- Expected result
- The single-digit fractions render as raised numerator, fraction slash and baseline denominator; the two-digit case only converts the digits adjacent to the slash, which is the documented limit rather than a bug.
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 — Fractions (frac) with numr and dnom” is a deterministic Novus Examples fixture for Conversion testing, Editor 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.
