Upgrading?

AI Summary

Enhanced PDF font parsing logic, specifically regarding script sizes and ToUnicode CMap repairs to improve accuracy.

Key Highlights

  • Improved sizing for super- and subscript runs based on glyphs
  • Skipped ToUnicode repairs for subset fonts with correct CMaps

New Features

  • Improved subscript/superscript sizing logic
  • Optimized subset font CMap repairs

Full Release Notes

Changes since 1.25.1:

- Size a super- or subscript run by its letters and digits: an exponent whose minus sign a symbol font sets a design size above its digits (as TeX does) keeps its `<sup>` markup; a run of signs alone, or with signs more than a quarter larger than its letters and digits, is still sized by its largest glyph (#603).
- Skip a subset font's ToUnicode repairs where the font itself shows the CMap is right: the repair through a `/CIDToGIDMap` for a CMap keyed by code, and the renumbering of a subset that kept its glyph indexes (#605).

No API changes.

Release preparation: #606.
