StringBuilder Encode Charset

Demonstrates the importance of the charset argument when encoding/decoding. Swift

func chilkatTest() {
    var s: String? = "é é é"

    let sb = CkoStringBuilder()!

    sb.append(value: s)
    sb.entityDecode()

    // The string now contains: "é é é"
    print("\(sb.getAsString()!)")

    // If encoded to hex using the iso-8859-1 charset, 
    // each é char is represented in 1 byte.
    // Output: E920E920E9
    print("\(sb.getEncoded(encoding: "hex", charset: "iso-8859-1")!)")

    // If encoded to hex using the utf-8 charset, 
    // each é char is represented in 2 bytes.
    // Output: C3A920C3A920C3A9
    print("\(sb.getEncoded(encoding: "hex", charset: "utf-8")!)")

    // Here's utf-16
    // Output: E9002000E9002000E900
    print("\(sb.getEncoded(encoding: "hex", charset: "utf-16")!)")

    // utf-32
    // Output: E900000020000000E900000020000000E9000000
    print("\(sb.getEncoded(encoding: "hex", charset: "utf-32")!)")
