Is there a native way to HTML escape character entities in javascript?

Question

The Unicode character 𠮵 given by point 134069, has the HTML escape 𠮵

Is there a (preferably native) way to get the HTML escapes for character entities from Javascript?

Answer 1

You can get both the point and hex values of the char like this:

var codePoint = '𠮵'.codePointAt(0); //codePoint = 134069
var hexValue = '𠮵'.codePointAt(0).toString(16); //hexValue = 20bb5
var htmlEscape = '&#x' + hexValue + ';'; //htmlEscape = 𠮵

Here is a working example:

$('#doIt').click(function() {
  $('#outputHex').html($('#inputText').val().codePointAt(0).toString(16));
  $('#outputString').html('&#x' + $('#inputText').val().codePointAt(0).toString(16) + ';');
  $('#outputChar').html('&#x' + $('#inputText').val().codePointAt(0).toString(16) + ';');
});

code {
  display: block;
  padding: 4px;
  background-color: #EFEFEF;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textarea id="inputText"></textarea>
<button id="doIt">do it</button>

<h3>result</h3>
<code id="outputHex"></code>
<code id="outputString"></code>
<code id="outputChar"></code>

One more thing, codePointAt is an ES6 function and isn't supported in older browsers. In case the browser blocks the code from running here: JSFiddle Example
