英文:
Emoji does not display in push Notification instead it display question mark or display unicode
问题
表情符号在推送通知中显示为Unicode字符。例如：如果我们有类似于"\ud83d\ude0a"的文本。这是笑脸表情符号的代码，它会显示为Unicode字符，有时在推送通知中显示为问号。
在代码或服务器端是否还需要做其他操作？任何帮助都将不胜感激。我们在后端使用Java。
JSON示例：
{
"to": "c2rMPP0eK04Ro0FJDgMflH:APA91bEydhoB0VU5W6PxJLnIRoFqOk5npEjlWzBlvdyBlX1Cp72t0bYxDyepP5Z9mWFQ2XYeUPw8PDo3QqT6Anh27wqnkBRbabTYKn0tByOZOMU6oRlrGur-efxN9_-8LlOmDZceg9Kl",
"notification": {
"body": "Hello",
"title": "This is done manually. \uD83D\uDE0A"
}
}
我们尝试了以下方法：
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)};
注意：如果我们从Postman中执行这些操作，它可以工作，但从后端执行时却无法工作。
英文:
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

"\uD83D\uDE0A" or "\u{D83D}\u{DE0A}" is not encoded emoji.
You should encode it like \u{1F600} \u{1F616}:
"\u{1F600} \u{1F616}"
Refer link:
It works on playground. Check if it works on the notification panel.
