将 Unicode 转换为表情符号的正确方法是什么？

Question

I have an array with Unicode data like var data = ["1F923", "1F603"] How can I convert Unicode to emoji?

If I use "\u{1F923}" in console, it returns an emoji, but if I use "\u{"+ data[0] +"}" , it returns an error. Can anyone please help me to convert unicode to emoji.

Answer 1

Emoji is a subset of unicode. There is no conversion from unicode to emoji necessary or possible. Just change your array to

var data = ["\u{1F923}", "\u{1F603}"]

If your input is a hex number, you can use

String.fromCodePoint(parseInt ("1F923", 16))

In HTML you can also use HTML hex entities

"&#x" + "1F923" + ";"

["

U can use this javascript function for unicode to emoji<\/i>

    var unicodeToChar = function(text) {
  return text.replace(/\\u[\dA-F]{4}/gi, function(match) {
      return String.fromCharCode(parseInt(match.replace(/\\u/g, ''), 16));
  });
}
