Encodeur / décodeur d'URL
Encodez et décodez du texte en URL avec la sémantique d'encodeURIComponent ou d'encodeURI, avec des erreurs claires en cas d'entrée mal formée.
Comment utiliser
Pick a mode, then Encode or Decode. Component mode matches encodeURIComponent: it escapes everything including separators like & and =, which is what you want for a query parameter value. Full URL mode matches encodeURI: structural characters such as :// and ? are left intact.
Remarques
Everything runs in your browser. Decoding input with an invalid percent-escape such as "%ZZ" shows an error. Note that "+" is not converted to a space here — that rule belongs to application/x-www-form-urlencoded form bodies, not to percent-encoding itself.
