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.

Swift

func chilkatTest() {
    var success: Bool = false

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

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

    // This is the URL encoding of the utf-8 representation.
    var nameUtf8UrlEncoded: String? = "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.
    let sb1 = CkoStringBuilder()!
    success = sb1.decodeAndAppend(value: nameWindows1252UrlEncoded, encoding: "url", charset: "windows-1252")

    let sb2 = CkoStringBuilder()!
    success = sb2.decodeAndAppend(value: nameUtf8UrlEncoded, encoding: "url", charset: "utf-8")

    // sb1 and sb2 both hold the same string.
    var bEqual: Bool = sb1.contentsEqualSb(sb: sb2, caseSensitive: true)
    print("bEqual = \(bEqual)")

    // We can see the string is "MÆRSK" in both cases.
    print("\(sb1.getAsString()!)")
    print("\(sb2.getAsString()!)")
