textproc/libgrapheme 3.0.0 NetBSD

libgrapheme is an extremely simple freestanding C99 library providing utilities for properly handling strings according to the latest Unicode standard 15.0.0. It offers fully Unicode compliant grapheme cluster (i.e. user-perceived character) segmentation, word segmentation, sentence segmentation, detection of permissible line break opportunities, case detection (lower-, upper- and title-case) and case conversion (to lower-, upper- and title-case) on UTF-8 strings and codepoint arrays, which both can also be null-terminated.
