Emojis support in Apple push notification

Question

I am working on iPhone app named \"INTERSTIZIO\".In this I have implemented functionality like chat between users.In this user can send text,location and text with emojis symbol

Answer 1

you shouldn't need to mess about with html decoding. As you say the code point for smiling face is \u263A. In PHP you can represent that in a UTF8-encoded string as "\xE2\x98\xBA"

Lightning bolt (actually 'high voltage sign') is \u26A1 or "\xE2\x9A\xA1" in UTF-8.

Both these characters are present in some non-emoji fonts as regular Unicode symbols. You can see with:

<?php
header('Content-type: text/html; charset=utf-8');
echo "\xE2\x9A\xA1";
echo "\xE2\x98\xBA";

I don't know where you got &#57661; from, but that would be \ue13d which is in an empty private use Unicode range, and not an Emoji within the Unicode standard Check it here Possibly it's from some other Japanese mobile carrier standard, but for iOS you should use Unicode.

You can get my above encodings from this table or use this Emoji search tool.

As for Apple push. This note says you can send emoji as UTF-8 encoded strings, so a json object like {"alert":"\u26A1SHOCKER\u26A1"} sounds like it will work.

Answer 2

for the googlers. json_encode() adds double \

$message = "\ue04a";
$body['aps'] = array(
                   'alert' => $message,
                   'sound' => 'default',
                   'type'  => $type,
                   'param' => $param
               );

$payload = json_encode($body);
$payload = str_replace("\", "\\", $payload);
