It is the foundation for SWI-Prolog's normalisation forms (NFC, NFD, NFKC, NFKD), case folding, grapheme-cluster iteration (UAX#29), and per-code-point property lookup (general category, bidi class, display width, combining class, case mappings, ...). The public Prolog API is exported from `library(unicode)`; see the predicates `unicode_nfc/2`, `unicode_property/2`, `atom_graphemes/2`, and friends for details. This is a git submodule of the main [swi-prolog/swipl-devel](https://github.com/SWI-Prolog/swipl-devel) repository. It builds only when the system has `libutf8proc` installed (available in every major package manager); the upstream utf8proc source is no longer vendored. Issues and pull requests specific to this binding belong here; Unicode-data bugs should be reported upstream at the utf8proc tracker.
