How to send a Firebase Cloud Messaging Notification with special characters like ä, ö, ü?

Question

I tried for a while to send a FCM Notification with special characters like this:

curl --header "Authorization: key=Auth-CODE" 
--header Content-Type:"application/json 
for JSON; application/x-www-form-urlencoded;charset=UTF-8" 
-d '{"to":"token","notification":{"title":"München",
"body":"Test Content with äöü",
"icon":"images/icon-192x192.png"}}' 
https://fcm.googleapis.com/fcm/send

The notification I'll get looks like this:

Mnchen
Test Content with

Can anybody please guide me to the right direction? Thanks a lot!

EDIT

The client is a browser, because the app is a web-App.

yes I tried this also... first urlencode the string and finally url_decode the received string... This always shows me *M%C3%BCnchen* — MPe, Dec 13 '16 at 08:08
@AL. The client is a browser, because the app is a web-App. (sorry I missed this info!) — MPe, Dec 13 '16 at 08:39
@LạngHoàng Thanks a lot! It seems to me that the changes need some time to take effect! — MPe, Dec 13 '16 at 20:00

According to @LangHoang I tried to use Base64 encode and decode to get a special character support!

<?php 
base64_encode ($string);

and decode the response in javascript (firebase-messaging-sw.js)

body:b64DecodeUnicode(payload.notification.body)

And now everything works very well!

With application/json;charset=UTF-8 should work. Had the same issue, that adding charset=UTF-8 to the Content-Type solved it.
