AI Summary

This release refines text sizing for superscripts and subscripts to match TeX standards and optimizes ToUnicode CMap repairs by skipping unnecessary checks.

Key Highlights

  • Size super/subscript runs by letters and digits to match TeX behavior
  • Skip ToUnicode repairs when the CMap is already correct
  • Handle runs of signs alone or with disproportionate sizing

New Features

  • Improved subscript/superscript sizing logic
  • Optimized ToUnicode CMap repair checks

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.
