How it works
- Accented/diacritic characters are normalized to their plain ASCII equivalent (e.g.
é→e,ü→u) using Unicode NFD decomposition. - Anything that isn't a letter or digit is treated as a word boundary and replaced with the chosen separator.
- Leading, trailing, and duplicate separators are collapsed/removed.
- Optionally, the result is lowercased (recommended for URLs and SEO).
