iOS Push notifications in cyrillic

Question

Hullo, I am sending push notifications by means of this php snippet:

// Build the binary notification
 $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
 $result = fwrite($fp, $msg, strlen($msg));

it works fine and good with latin languages but, when I try to send a russian notification, nothing arrives, notwithstanding the logs confirm the correct delivery.

Any idea about what to do to fix it?

Answer 1

I think the optimal solution is to send english strings and localize them in the app. The only downsize of it is that you need to submit an update each time you want to add a new notification type.

Answer 2

Your code looks good and I'm leaning towards a "size" problem. Try using mb_strlen in your code instead of strlen as strlen cannot accurate calculate length of multi-byte characters.
