    I had the same problem. It might differ depending on how You put the data to the db, but try what worked for me:

    $str = json_encode($data);
$str = addslashes($str);

    Do this before saving data to db.

    Work for me :)

    function jsonEncodeArray( $array ){
    array_walk_recursive( $array, function(&$item) { 
       $item = utf8_encode( $item ); 
    });
    return json_encode( $array );
}

    If your source-file is already utf8 then drop the utf8_* functions. php5 is storing strings as array of byte.

    you should add a meta tag for encoding within the html AND you should add an http header which sets the transferencoding to utf-8.

    <html>
<head>
   <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

    and in php

    <?php
header('Content-Type: text/html; charset=utf-8');

    This is an encoding issue. It looks like at some point, the data gets represented as ISO-8859-1.

    Every part of your process needs to be UTF-8 encoded.

    • The database connection

    • The database tables

    • Your PHP file (if you are using special characters inside that file as shown in your example above)

    • The content-type headers that you output
