How to convert one emoji character to Unicode codepoint number in JavaScript?

how to convert this 😀 into this 1f600 in javascript

'😀'.charCodeAt(0);

this will return unicode 55357 but how to get 1f600 from 😀

Solution

  • Added script to convert this on browser side

    function emojiUnicode (emoji) {
    var comp;
    if (emoji.length === 1) {
        comp = emoji.charCodeAt(0);
    }
    comp = (
        (emoji.charCodeAt(0) - 0xD800) * 0x400
      + (emoji.charCodeAt(1) - 0xDC00) + 0x10000
    );
    if (comp < 0) {
        comp = emoji.charCodeAt(0);
    }
    return comp.toString("16");
};
emojiUnicode("😀"); # result "1f600"
