## [0.8.1] - 2026-05-21

### Fixed
- **CID TrueType text extraction** — `ExtractTextFromPage()` now correctly decodes CID TrueType fonts with Identity-H encoding and ToUnicode CMap (#74, @iv7dev)
- Implemented `beginbfrange` array format parsing (previously silently skipped, producing empty CMap)
- Fixed `use2ByteGlyphs` detection for Identity-H encoding in all `loadFontDecoder` fallback paths
- Added `begincodespacerange` parsing to determine byte width from the PDF spec-defined signal
- Added UTF-16BE surrogate pair decoding in CMap destinations (for supplementary Unicode planes)
- Prevented `looksLikeGarbage` heuristic from downgrading composite (Type0) fonts to 1-byte mode
