How are accented characters like é or ñ handled?

Diacritics are stripped so accented letters fall back to their plain ASCII form (é becomes e, ñ becomes n) before the rest of the slug rules apply, since most URL/SEO conventions prefer plain ASCII slugs for maximum compatibility.

Are numbers and existing hyphens kept in the slug?

Yes, digits are preserved as-is, and existing hyphens are treated the same as spaces or other separators — collapsed into a single hyphen. Leading and trailing hyphens are trimmed from the final result.
