AI Summary

Fixes critical font decoding issues where text was misread or lost, specifically addressing two-byte codespace declarations, custom Type1 encodings, and unreliable CMap repairs.

Key Highlights

  • Fixed text decoding for simple fonts with two-byte codespace declarations
  • Added support for Type1 fonts with custom /Encoding (ligatures, math symbols)
  • Improved reliability of ToUnicode CMap repairs by requiring stronger evidence

New Features

  • Fixed font decoding for kerned runs
  • Added support for custom Type1 encoding

Full Release Notes

Changes since 1.25.0:

- Read simple fonts (Type1, TrueType, Type3) one byte per code when their ToUnicode CMap declares a two-byte codespace: text shown as a kerned run of short strings no longer loses every two-byte string (`Income Statement` read as `Iometatent`). The stale-CMap check for Type1 fonts judges such a CMap too, and the page detector counts such a font's text byte by byte (#595).
- Read a Type1 font whose `/Encoding` names no base encoding through the built-in encoding of its embedded program (PDF 32000-1:2008, Table 114): TeX's fonts read their ligatures (`efficiency`, was `eciency`), curly quotes, dashes and math symbols. A code the program leaves at `.notdef` reads as nothing, the word space excepted, and the base-14 width fallback measures such fonts as they read (#596).
- Take a repaired ToUnicode CMap for a string of one or two glyphs only on evidence beyond short common words: `engagement` no longer reads as `engageaent`, `AND` as `ANa` or `Three` as `ThaTe` (#597).

No API changes.

Release preparation: #604.
