Tags: eslint, linting, code-quality, automation, unicode

Score: 5.0/10 (Innovation: 4, Technical: 3, Documentation: 8, Utility: 5)

An ESLint plugin that automatically detects and fixes Unicode em dashes (U+2014) in codebases, replacing them with plain hyphens. It's interesting because it addresses a specific, modern pain point caused by AI-generated code and document editors leaking non-ASCII punctuation into source files, which can break tooling and create inconsistency.

Target audience: frontend devs, backend devs, full-stack devs
