AI Summary

Fixes script size calculations and ToUnicode repair checks for PDF fonts.

Key Highlights

  • Size super- and subscript runs by letters and digits correctly
  • Skip subset font ToUnicode repairs when CMap is already correct
  • Handle exponent minus sign in symbol fonts properly
  • Fix font glyph indexing for subset fonts
  • Improve TeX-like design size handling for superscripts

New Features

  • Intelligent sizing for super/subscript runs based on character content
  • Smart ToUnicode repair skipping for valid CMaps
  • Better handling of symbol fonts with design sizes
  • Improved glyph index renumbering for subset fonts

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.
