プロジェクトの歴史

John Walker published the Fourmilab unum page in February 2006. The page presents unum as a standalone portable Perl program that removes the need to manually consult Unicode tables, HTML entity references, and programmer calculators when preparing web documents or source text.

The utility remained maintained as Unicode and HTML entity data changed. The Fourmilab page lists multiple updates from 2017 through 2023 and identifies version 3.6-15.1.0 as released on October 21, 2023, with character tables based on Unicode 15.1.0.

採用の歴史

unum appears in Homebrew as a niche developer utility rather than a broad platform tool. Its adoption story is mostly the durable packaging of a single-file Perl reference program for users who want Unicode and entity lookups available from a shell.

使われ方

The tool is used to answer questions such as converting code points between bases, finding the Unicode name for a character, looking up HTML entities, decoding UTF-8 byte sequences, and listing Unicode blocks. Fourmilab documents installation as placing the single unum.pl file somewhere on PATH, with Perl and optionally bunzip2 as the main runtime requirements.

パッケージ好きにとっての重要性

For package-nerd workflows, unum is the kind of low-dependency utility that survives because it is scriptable, portable, and focused. It is useful when packaging documentation, terminals, web pages, or source files expose encoding details that are easier to inspect from a CLI than from a browser or GUI character map.
