Json encode with accents

Question

I have an hidden element that receives a JSON string from a multidimensional array. When I try to get this string it returns null because of some accents. The original array is ISO-8859-1. How can I adjust this? It will be parsed with JS to populate a select field.

PHP - data source

$SubjectListChild1 = array(array ('Code' => 1, 'MainLabel' => 'Dúvidas sobre o processo'));
$data = json_encode($SubjectListChild1);

JS - getting data

var childSubject = (jQuery('#SubjectListChild').html());
var obj = jQuery.parseJSON(childSubject);

Answer 1

Have a look into utf8-encoding the array strings: utf8_encode($string)

json_encode only works on utf-8 encoded data.

Edit: It's possible you can serialize the array, utf-8 encode it, and unserialize it. But I haven't tested this.
