Summary

Warp 0.2 (font version 0.200) makes Warp a maths font and covers the Central European and Baltic languages.

• OpenType MATH table in all six fonts: constants, four size variants and assemblies for delimiters, radicals and integrals, italic corrections and accent positions. Set with LuaLaTeX and unicode-math (proofs/warp/warp-math.png).
• Latin Extended-A and Ș ș Ț ț, with marks drawn by the pen. Polish, Czech, Slovak, Hungarian, Romanian, Turkish, Croatian, Slovenian and the Baltic languages are covered.
• Greek tonos and dialytika. Superior and inferior figures, numerators and denominators (sups, subs, sinf, numr, dnom, frac).
• Italic capitals B D E F H I J K L P R S T U X Y Z and & with their own cursive forms.
• Small-size reading: closed g, firmer f, fi and fl bars that stop short, wider word space at text size, heavier Ξ and Σ.
• Kerning for more lowercase, Greek and italic pairs.
• TTF hinted with ttfautohint 1.8.4, byte-reproducible.
• Docs: warp/CHANGELOG.md, warp/RELEASE-NOTES-0.2.md, warp/STATUS.md (done, open, accepted WARNs). Specimen page links releases/tag/warp-v0.2.0.

Checks

Run locally on commit a5d6720. The workflow warp.yml runs on pushes to main and on pull requests, so it has not run on this branch yet.

Review

• Proofs: every PNG in proofs/warp/ was looked at. Changed and new sheets: warp-math.png, warp-accents.png, warp-latin-ext.png, warp-kerning.png (the sheet was clipped; fixed in tools/proof.py), warp-italic-caps.png, warp-greek.png, warp-before-after.png, warp-smallcaps-figures.png, warp-equations.png, and the six warp-charset-*.png and warp-sketch-vs-font-*.png sheets.
• Deliberate deviations from the sketch are in warp/STATUS.md. The italic capitals are the main one. The sketch-compare test now leaves them out for the italics. The sketch IoU is 0.94 for the other italic glyphs.
• Open items (STATUS.md): italic at 10 px (v, c, e), Æ Œ Ø and the Greek capitals in the italic, no math kerning or ssty, no stretchy horizontals, no hinting in the OTF.
• The branch was not merged, no tag was made, and no release was published.
