v0.3.69 | Language-bindings release — idiomatic bindings for **C++, Swift, Kotlin, Dart, R, Julia, Zig, Scala, Clojure, Objective-C, and Elixir**, each over the stable C ABI, with per-language CI, package-registry publishing, cross-language regression examples, and single-source version management.

Added

• Eleven new language bindings, each with an idiomatic wrapper, an api-coverage test (one assertion per public method), runnable CI-asserted examples, a README with install coordinates, and a dedicated CI workflow (Linux+macOS) running the same verification set:
  • C++ (cpp/) — header-only C++17 RAII wrapper; CMake with install/export targets and a Conan recipe.
  • Swift (swift/) — SwiftPM package + C module map.
  • Kotlin (kotlin/) — thin facade over the Java JNI binding.
  • Dart/Flutter (dart/) — dart:ffi.
  • R (r/) — .Call C shim, external-pointer handles.
  • Julia (julia/) — ccall.
  • Zig (zig/) — @cImport.
  • Scala (scala/) — thin facade over the Java JNI binding (Scala 3).
  • Clojure (clojure/) — direct Java interop over the JNI binding.
  • Objective-C (objc/) — NSObject wrappers over the C ABI.
  • Elixir (elixir/) — dirty-scheduler NIF (CPU-bound work never blocks the BEAM).
• Package-registry publishing wired into the release pipeline for the new bindings: Maven Central (Kotlin, Scala), Clojars (Clojure), Hex.pm (Elixir), and pub.dev (Dart, via GitHub OIDC). Objective-C ships as a Trunk-free CocoaPods binary pod — an xcframework + podspec uploaded as release assets and installed via a :podspec URL — since CocoaPods Trunk goes read-only on 2026-12-02. C++ (vcpkg/Conan), R (CRAN), Julia (General registry), and Swift/Zig (git tag) are documented in docs/RELEASING-bindings.md.
• Cross-language regression examples — alongside each binding's basic example, three shared-scenario examples (HTML extraction, word geometry, table extraction) run with output assertions in every binding's CI workflow.
• Single-source version management — scripts/sync_version.py propagates the canonical Cargo.toml version into every binding manifest and version/parity assert (--check verifies, --set X.Y.Z bumps everything). A Version Consistency CI workflow fails if any binding drifts.

Fixed

• Non-Identity-ordered Type0 fonts no longer emit a wrong character for CIDs missing from /ToUnicode (#773, #775) — for an embedded Type0 font whose /ToUnicode CMap omits some drawn CIDs (e.g. a ligature glyph with no single Unicode codepoint), the decode path fell back to a numeric guess — the GID via the standard glyph-name table → AGL, or the CID itself as a code point (char::from_u32) — emitting a plausible-but-wrong, content-like character that varied per subset (e.g. a ti ligature → : / D, so notificacao → no:ficacao). The glyph has no Unicode anywhere in the file (no /ToUnicode entry, no post name, no GSUB), so the letters are unrecoverable, but substituting a wrong character is silent corruption. When a usable /ToUnicode is present, the GID→AGL guess is now suppressed for all Type0 fonts, and the CID-as-Unicode guess is suppressed for fonts whose CIDSystemInfo ordering is not Identity, so an uncovered CID there decodes to U+FFFD instead. For Identity-ordered (Adobe-Identity-0) fonts the CID-as-Unicode guess is restricted to whitespace (U+0020 → space, which producers routinely omit and is reliably CID == codepoint); any other uncovered CID likewise decodes to U+FFFD. A font with no /ToUnicode still uses the CID-as-Unicode heuristic exactly as before, and the authoritative embedded-cmap/post lookups are unchanged. This also resolves the opt-in-flag request (#775) by making the detectable-gap behaviour the default rather than a configuration flag. Thanks @schelip for reporting both issues and contributing the fix.
