Its feature set includes Unicode Character Database property access, UTF-8 and UTF-32 conversion, wcwidth-style width calculation, grapheme segmentation, emoji and script segmentation, word segmentation, and a unicode-query command-line tool. The v0.1.0 release on November 3, 2022 called itself an initial release after two and a half years and said the project had already been actively used by Contour Terminal. Later tags show a steady 0.x progression through v0.9.0 on April 9, 2026. ### Adoption history The README names Contour Terminal Emulator as a user of the library. That adoption path explains the library's emphasis on terminal-relevant Unicode details such as grapheme clusters, width, variation selectors, emoji behavior, and text-run segmentation. Packaging in Homebrew and other Unix-like package sets gives developers a small C++ alternative to larger Unicode stacks when they want terminal- or text-processing-oriented Unicode support without adopting ICU's older C/C++ API style. ### How it is used Developers can add libunicode as a submodule or CMake dependency and link against unicode::unicode. Users can inspect text with the unicode-query CLI, while applications use the library for width decisions, segmentation, conversion, and Unicode property lookup. ### Why package nerds care libunicode is package-nerd significant as a terminal-driven Unicode library: it focuses on the messy details that make modern terminal rendering hard, especially grapheme clusters, emoji sequences, variation selectors, and wcwidth-like behavior. ### Timeline - 2020: The v0.1.0 release note says the first commit was in May 2020. - 2022: v0.1.0 was released on November 3, 2022 after active use in Contour Terminal. - 2023: v0.3.0 was tagged on March 1, 2023 and v0.4.0 on November 27, 2023. - 2024: v0.6.0 was tagged on September 30, 2024. - 2026: v0.9.0 was released on April 9, 2026 with normalization, segmentation, and SIMD conversion work. ### Related projects - Contour Terminal Emulator is the primary named user and sibling project. - Terminal Unicode Core is a related Contour specification addressing grapheme clusters, variation selectors, and cursor placement. - ICU is the larger mature Unicode library that libunicode explicitly contrasts itself with in the README. ### Sources -
