Upgrading?

AI Summary

A patch release addressing font size calculations and ToUnicode repair checks to improve text extraction accuracy.

Key Highlights

  • Improved size calculation for superscripts and subscripts based on letters and digits
  • Optimized ToUnicode repairs to skip subset fonts with correct CMaps

New Features

  • Better handling of symbol fonts in exponents
  • Smarter ToUnicode repair logic

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.
