<h2 id="Summary" name="Summary">Sommario</h2>

<p>La funzione <strong><code>unescape()</code></strong>, deprecata, crea una nuova stringa nella quale le sequenze di escape esadecimali vengono sostituite con il loro carattere corrispondente. Le sequenze di escape potrebbero essere state generate da funzioni simili a {{jsxref("Global_Objects/escape", "escape()")}}. Essendo <code>unescape()</code> deprecata, è preferibile utilizzare le funzioni {{jsxref("Global_Objects/decodeURI", "decodeURI()")}} o {{jsxref("Global_Objects/decodeURIComponent", "decodeURIComponent()")}}.</p>

<div class="note"><strong>Nota:</strong> Non usare la funzione <code>unescape()</code> per decodificare degli {{Glossary("URI")}}, usa {{jsxref("Global_Objects/decodeURI", "decodeURI()")}}.</div>
