+<p>La función deprecada <code><strong>unescape()</strong></code> calcula un nuevo string  en el cual secuencia de valores hexadecimales son reemplazados con el caracter que representa. La secuencia de calculo deber{ia ser introducida por una función como {{jsxref("escape")}}. Por que <code>unescape</code> está deprecada, usar {{jsxref("decodeURI")}} or {{jsxref("decodeURIComponent")}}.</p>
