UTF8 support on android: the notification text (on android only) is shown with "???"

[yoav-zibin]

Hi,
Have you ever tested non-english notifications on android? I tried both Hebrew and Chinese, and it doesn't work.

I'm sending the same notification text to GCM and APNS, and it is shown correctly on iphone, but not android.
See the attached printscreens:
On android it is shown with "?????" :

On iOS it is shown correct:

I captured a bug report and this is what I see:
12-27 12:38:55.650 21639 21679 D PushPlugin_GCMIntentService: replace key collapse_key with collapse_key
12-27 12:38:55.650 21639 21679 D PushPlugin_GCMIntentService: background
12-27 12:38:55.650 21639 21679 D PushPlugin_GCMIntentService: message =[yoav local chrome ????? ???? ?????]
12-27 12:38:55.650 21639 21679 D PushPlugin_GCMIntentService: title =[???? ???]
12-27 12:38:55.650 21639 21679 D PushPlugin_GCMIntentService: contentAvailable =[null]

When I sent to GCM, I use AppEngine, and I logged the exact post message:

I'm pretty sure the problem is here:

phonegap-plugin-push/src/android/com/adobe/phonegap/push/GCMIntentService.java

Line 147 in 20f489a

Object json = extras.get(key);

I believe this:
Object json = extras.get(key);
should be:
String json = URLDecoder.decode(extras.get(key).toString(), "UTF-8");

(I'm using phonegap build, so I can't really test if this solution works :))

Never mind! I found the solution to do it on the server side:
http://stackoverflow.com/questions/22861828/java-string-getbytesutf-8-javascript-equivalent

I had to use both:
Content-Type: application/json;charset=UTF-8

AND:
byte[] bytes = message.getBytes("UTF-8");
OutputStream out = connection.getOutputStream();
try {
out.write(bytes);
} finally {
out.close();
}

(before I was writing the string directly, and not the bytes).

Hope it will help someone else :)
