(Node.js) Decode from Binary Encoding and Append String

Demonstrates how to decode from a binary encoding (base64, hex, url, etc.) and then append the decoded string to a Chilkat StringBuilder object.

Note: This example uses the new DecodeAndAppend method added in Chilkat v9.5.0.87.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOSX, and ARM

function chilkatExample() {

    // We have the string "MÆRSK" in two forms:

    // This is the URL encoding of the windows-1252 representation.
    var nameWindows1252UrlEncoded = "M%C6RSK";

    // This is the URL encoding of the utf-8 representation.
    var nameUtf8UrlEncoded = "M%C3%86RSK";

    // Note that the result of loading a string into a string object 
    // is the same if we correctly specify the underlying charset encoding.
    // In the above example, we have the same string, but in different charset encodings
    // subsequently URL encoded.
    var sb1 = new chilkat.StringBuilder();
    var success = sb1.DecodeAndAppend(nameWindows1252UrlEncoded,"url","windows-1252");

    var sb2 = new chilkat.StringBuilder();
    success = sb2.DecodeAndAppend(nameUtf8UrlEncoded,"url","utf-8");

    // sb1 and sb2 both hold the same string.
    var bEqual = sb1.ContentsEqualSb(sb2,true);
    console.log("bEqual = " + bEqual);

    // We can see the string is "MÆRSK" in both cases.
    console.log(sb1.GetAsString());
    console.log(sb2.GetAsString());
