This is my query; in my db all leanguage is set to utf8_general; this query return null if some character are present, don't know if only accent
require_once('db_connect.php');
$sql = "SELECT avwp_posts.id, cast(avwp_posts.post_content as char(200) ) AS post_content, cast(avwp_posts.post_title as char(60) ) AS post_title, avwp_posts.post_type, avwp_posts.post_date_gmt, avwp_users.display_name as nicename FROM avwp_posts JOIN avwp_users ON (avwp_posts.post_author=avwp_users.id) WHERE post_type='post' AND post_status='publish' ORDER BY post_date_gmt DESC";
$result = $con->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$myArray[] = $row;
echo $myArray['post_content'];
}
}else {
echo json_encode("NOTOK");
}
echo json_encode($myArray);
$con->close();
This is the result of the query

If i get with substring (char(200)) a portion of char that doesn't have accent it return a value, else it return null
This is the var_dump result

As you can see here i have all the data, why the json_encode set them to null??
