Its package history is the classic Unix-library story: a narrow text-processing primitive, a manpage-driven CLI, and distribution through source tarballs and OS packages. ### Historique du projet The official README describes unac as a C library plus the `unaccent` command. The code history on Savannah shows active early-2000s maintenance by Loic Dachary, with releases around Unicode data updates, iconv portability, bug fixes, and manual-page improvements. The official NEWS file records version 1.8.0 upgrading to Unicode 4.0, version 1.7.0 fixing a Unicode 3.2 bug, and version 1.6.0 upgrading to Unicode 3.2.0. The ChangeLog records release activity from 2000 through 2004, which frames unac as mature legacy infrastructure rather than a fast-moving modern text stack. ### Historique d'adoption The official project page announced Debian and RPM packages in the early 2000s, and the input package metadata lists Homebrew, MacPorts, Debian, and Ubuntu package names. That is the relevant adoption story: unac became a distro-packaged text-normalization dependency and command rather than a highly visible end-user tool. ### Modes d'utilisation The README says the input charset must be specified, after which unac converts text to UTF-16 with iconv, removes accents, and converts the result back. The `unaccent` command can process an input flow or a string argument, making it useful in shell pipelines and indexing/import scripts. Package users reach for unac when they need a tiny native accent-folding tool without pulling in a larger application framework. The tradeoff is that it reflects older Unicode and iconv-era design assumptions. ### Pourquoi les passionnés de paquets s'y intéressent unac is significant in the package-nerd niche because it preserves a focused pre-ICU style Unix component: a C library, manpages, autotools build, and a single CLI that does one text-normalization job. It is not a major ecosystem pillar, but it is the sort of small dependency that matters when old software, search systems, or packaging recipes still expect `unaccent` behavior. ### Chronologie - 2000: ChangeLog records unac 1.2.0 release activity. - 2001: Versions 1.3.0, 1.4.0, and 1.5.0 appear in the official ChangeLog and NEWS. - 2002: Versions 1.6.0 and 1.7.0 update Unicode support and bug handling. - 2004: Version 1.8.0 upgrades to Unicode 4.0. ### Related projects - Text-Unaccent and phpUnac were released alongside unac in early project announcements. - iconv and GNU libiconv are central related components because unac relies on charset conversion before accent removal. ### Sources - - - - - source_facts.package-manager ## Notes de sécurité library-like package without higher-risk signals. - **Risque Geiger:** vert / faible - library-like package without higher-risk signals ## Autres enregistrements de gestionnaires de paquets - Debian apt - libunac1 - 1.8.0-10+b3: normalized package name match | Debian stable package indexes: libunac1 from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | unac programming library - runtime version - Debian apt - libunac1-dev - 1.8.0-10+b3: normalized package name match | Debian stable package indexes: libunac1-dev from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | C programmer's library that removes accents from a string - Debian apt - unaccent - 1.8.0-10+b3: normalized package name match | Debian stable package indexes: unaccent from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Replace accented letters by their unaccented equivalent - Ubuntu apt - libunac1 - 1.8.0-10: normalized package name match | Ubuntu 24.04 LTS package indexes: libunac1 from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | unac programming library - runtime version - Ubuntu apt - libunac1-dev - 1.8.0-10: normalized package name match | Ubuntu 24.04 LTS package indexes: libunac1-dev from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | C programmer's library that removes accents from a string - Ubuntu apt - unaccent - 1.8.0-10: normalized package name match | Ubuntu 24.04 LTS package indexes: unaccent from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Replace accented letters by their unaccented equivalent - MacPorts - unac: normalized package name match | MacPorts ports tree: textproc/unac/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
