Changelog

Semantic versioning. Dates are UTC.

• 0.4.22026-10-12

  WOFF2 files are now decompressed in-process, so you no longer need a separate woff2_decompress on the PATH. Fixed a panic on fonts whose cmap had a format-13 subtable (some CJK builds).

• 0.4.02026-08-30

  New missing --text command: report every codepoint in a text sample the font can't draw, with line numbers. coverage --json output is now stable and documented.

• 0.3.12026-06-04

  show picks up terminal width from $COLUMNS and wraps the glyph grid instead of overflowing. Block names now follow Unicode 16.0.

• 0.3.02026-04-18

  Added diff. Coverage is computed from the cmap directly rather than enumerating glyph ids, which fixed over-counting on fonts with unmapped glyphs.

• 0.2.02026-02-02

  TTC support with --index. Terminal preview gained the dimmed-for-missing rendering.

• 0.1.02024-11-10

  First public release: coverage and show, TTF/OTF only.
