This simple php function converts recursively all values of an array to UTF8.
The function mb_detect_encoding (line 4) checks if the value already is in UTF8, this way it will not reconvert.

function utf8_converter($array)
{
    array_walk_recursive($array, function(&$item, $key){
        if(!mb_detect_encoding($item, 'utf-8', true)){
                $item = utf8_encode($item);
        }
    });
 
    return $array;
}
