Answer 1

A hacky way of doing JSON_UNESCAPED_UNICODE in PHP 5.3. Really disappointed by PHP json support. Maybe this will help someone else.

$array = some_json();
// Encode all string children in the array to html entities.
array_walk_recursive($array, function(&$item, $key) {
    if(is_string($item)) {
        $item = htmlentities($item);
    }
});
$json = json_encode($array);

// Decode the html entities and end up with unicode again.
$json = html_entity_decode($rson);

Answer 2

try setting the utf-8 encoding in your page:

header('content-type:text/html;charset=utf-8');

this works for me:

$arr = array('tag' => 'Odómetro');
$encoded = json_encode($arr);
$decoded = json_decode($encoded);
echo $decoded->{'tag'};
