v0.0.1

0.0.1 (2026-10-23)

The first release: Unicode algorithms and character properties from
Unicode 18.0.0, passing every official conformance file for the
algorithms it implements.

Added

• UTF-8, UTF-16 and UTF-32 validation that names each kind of error
  and its offset, decoding and encoding of single code points, and
  conversions between the three, strict or with U+FFFD for each
  maximal ill-formed subpart.
• Character properties for any code point: General_Category, the
  segmentation and line breaking classes, East_Asian_Width, Bidi_Class,
  mirroring and bracket pairs, combining classes, Script and
  Script_Extensions, the emoji properties, White_Space,
  Default_Ignorable_Code_Point and decimal digit values.
• Grapheme cluster, word and sentence boundaries (UAX #29) and line
  break opportunities (UAX #14), through iterators on the caller's
  stack that take text in pieces, or into arrays. A caller's word
  segmenter can break Thai, Lao, Khmer and Burmese.
• The bidirectional algorithm (UAX #9) in two bytes of caller memory
  per byte of text, with line ordering and visual maps.
• Script runs for shaping, and maul-unicode-harfbuzz, which gives
  HarfBuzz its Unicode data from the library.
• Normalization to NFC, NFD, NFKC and NFKD with quick checks; case
  mapping and folding with the full mappings, Final_Sigma and the
  Turkic and Lithuanian rules; NFKC_Casefold.
• Identifier properties and checks (UAX #31), confusable skeletons,
  resolved script sets, restriction levels and mixed-number detection
  (UTS #39).
• Build options to leave out normalization, case and security with
  their tables, a shared library option, a CMake package and
  pkg-config modules.
• Support for Linux, macOS, Windows with clang-cl, and WebAssembly.
