FAQ
Frequently asked questions
How does diacritic stripping work?
Diacritic stripping decomposes accented characters using Unicode NFD normalisation, then removes the combining accent marks. For example, é becomes e, ñ becomes n, and ü becomes u. This makes slugs ASCII-safe and universally readable in URLs.
What happens to the slug when max length is set?
When max length is set, the slug is truncated at that character count and any trailing separator is removed. For example, with max length 10, 'hello-world-foo' becomes 'hello-worl' if the cut falls mid-word. The separator is never the last character of a truncated slug.
When should I use hyphen versus underscore as separator?
Choose hyphen (-) for standard web URLs — it is what Google recommends for SEO and it is the most widely recognised word separator in URLs. Choose underscore (_) when your system treats hyphens as part of a word (some databases and legacy APIs do).
What happens if the input produces an empty slug?
If no slug-safe characters remain after stripping (for example, if the input contains only emoji or punctuation with diacritics stripped), the tool returns an error rather than an empty string. Adjust your input or disable diacritic stripping to preserve characters.
