Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var s = "&eacute; &#233; &#xE9;";

var sb = new CkStringBuilder();

sb.Append(s);
sb.EntityDecode();

// The string now contains: "é é é"
console.log(sb.GetAsString());

// If encoded to hex using the iso-8859-1 charset, 
// each é char is represented in 1 byte.
// Output: E920E920E9
console.log(sb.GetEncoded("hex","iso-8859-1"));

// If encoded to hex using the utf-8 charset, 
// each é char is represented in 2 bytes.
// Output: C3A920C3A920C3A9
console.log(sb.GetEncoded("hex","utf-8"));

// Here's utf-16
// Output: E9002000E9002000E900
console.log(sb.GetEncoded("hex","utf-16"));

// utf-32
// Output: E900000020000000E900000020000000E9000000
console.log(sb.GetEncoded("hex","utf-32"));
