Emoji 不显示在推送通知中，而是显示问号或显示 unicode [英] Emoji does not display in push Notification instead it display question mark or display unicode

问题描述

表情符号在推送通知中显示为 unicode 字符.即:如果我们有像\ud83d\ude0a"这样的文本.这是SMILE EMOJI的代码，显示为unicode字符或有时在推送通知中显示问号.

在代码或服务器端还有什么需要做的吗??任何帮助，将不胜感激.我们在后端使用java

Json 示例:

<代码>{"到" ;:" c2rMPP0eK04Ro0FJDgMflH:APA91bEydhoB0VU5W6PxJLnIRoFqOk5npEjlWzBlvdyBlX1Cp72t0bYxDyepP5Z9mWFQ2XYeUPw8PDo3QqT6Anh27wqnkBRbabTYKn0tByOZOMU6oRlrGur-efxN9_-8LlOmDZceg9Kl" ;,通知":{身体":你好"，标题":这是手动完成的.\uD83D\uDE0A"}}

我们尝试这些东西

byte[] emojis = user.getEmoji().getBytes();String emojisAsString = new String(emojis, StandardCharsets.UTF_8);整数 emojiCodePoint = emojisAsString.codePointAt(emojisAsString.offsetByCodePoints(0,0));char emojiChars[] = {Character.highSurrogate(emojiCodePoint), Character.lowSurrogate(emojiCodePoint)};

注意:如果我们从邮递员那里解雇这些东西，那么它可以工作，但不能从后端触发时工作

解决方案

试试这个字符串:

"\u{D83D}\u{DE0A}"

Emoji appears as a unicode characters in push notifications. i-e : if we have text like "\ud83d\ude0a". This is the code of SMILE EMOJI which displays as unicode characters or some time it display question mark in push notification.

Is there anything else need to do in code or on server side. ? Any help would be appreciated. we are using java at backend side

Json example :

{
   "to": "c2rMPP0eK04Ro0FJDgMflH:APA91bEydhoB0VU5W6PxJLnIRoFqOk5npEjlWzBlvdyBlX1Cp72t0bYxDyepP5Z9mWFQ2XYeUPw8PDo3QqT6Anh27wqnkBRbabTYKn0tByOZOMU6oRlrGur-efxN9_-8LlOmDZceg9Kl",
   "notification": {
      "body": "Hello",
      "title": "This is done manually. \uD83D\uDE0A"
   }
}

We try this things

byte[] emojis = user.getEmoji().getBytes();
String emojisAsString = new String(emojis, StandardCharsets.UTF_8);
Integer emojiCodePoint = emojisAsString.codePointAt(emojisAsString.offsetByCodePoints(0,0));
char emojiChars[] = {Character.highSurrogate(emojiCodePoint), Character.lowSurrogate(emojiCodePoint)};

Note : If we fire this things from postman then it is working but not working when it fire from backend

解决方案

Try this string:

"\u{D83D}\u{DE0A}"
