AI Summary

Fixes script sizing logic for superscripts and subscripts, and optimizes ToUnicode repair checks to skip unnecessary repairs when the CMap is already correct.

Key Highlights

  • Sizes super- or subscript runs by letters and digits, preserving minus sign markup
  • Skips ToUnicode repairs for subset fonts where the CMap is already correct
  • No API changes

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.
