[4.2.1] - 2026-07-22

Fixed

• Flat-path separator heuristics measured pen movement in post-CTM user space, corrupting line structure under a rotated CTM (#443). A plain forward advance along a rotated baseline changes the user-space y, which the newline gate misread as a line change (spurious newlines everywhere), and the rotation gave every same-baseline glyph a nonzero Δy, defeating the #441 same-line gate. Pen deltas are now projected onto the current text baseline direction (the image of the text-space x-axis under Tm × CTM): Δx along the baseline, Δy perpendicular to it. For axis-aligned content the projection is exactly the previous Δx/Δy — no behavior change — and under rotation it recovers the text's own line geometry, so all the Tj/TJ separator gates (newline threshold, space threshold, backward-jump wrap) now hold for rotated text. Mirrored (negative-x-scale) baselines now measure Δx along the text's own advance direction, so plain forward advances no longer misfire the backward-jump wrap gate. Axis-aligned shear projects exactly; shear combined with a rotated baseline is approximated. The tracked pen position is the full post-advance point, so rotated baselines advance y as well as x. Degenerate (zero-length or non-finite) baselines fall back to raw user-space deltas. The two line-structure invariants pinned to #443 (rotation property + 20° deterministic pin) flip from #[ignore] to permanent guards.
• A same-line backward X jump was misread as a line wrap (#441). The flat-path heuristic added for #390 treated any backward pen jump beyond 2× newline_threshold as a wrap, ignoring Δy — so glyphs repositioned backward on the same baseline (justification, out-of-order emission) gained a spurious newline mid-word. In axis-aligned text a wrap always lands on a different baseline: the heuristic now also requires a nonzero Δy, in both the Tj and TJ handlers. Tight-leading wraps (small but nonzero Δy, the #390 class) still break. (Rotated/sheared CTMs were initially outside this gate's reach; closed by the #443 fix above in this same release.) A new line-structure property invariant guards both directions — spurious and missing newlines — against generated layouts whose true line structure is known by construction.

[4.2.0] - 2026-07-21

Fixed

• A lone space decoded from /ToUnicode was discarded as garbage (#438). Both /ToUnicode paths tested a decode for usability by trimming it first, so a code mapping to exactly U+0020 trimmed to empty and was rejected — the extractor then fell back to the raw code and emitted the byte as a literal ASCII character, corrupting word boundaries in subsetted-font documents. The simple-font and CID paths had diverging copies of that predicate; they now share one, and a decode is unusable only when it produced no characters at all or nothing but non-whitespace control codes. Whitespace is real text. The
