Unicode Escape

Convert a string to Unicode escaped values. Swift

func chilkatTest() {
    var success: Bool = false

    let sb = CkoStringBuilder()!

    var str: String? = "bôn"
    var charset: String? = "not_used"

    // Unicode escape all chars using \uHHHH
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-all", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is \u0062\u00f4\u006e

    // Unicode escape only 8bit chars using \uHHHH
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-8bit", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is b\u00f4n

    // To use uppercase hex chars (A-F), add "-upper" to the encoding name
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-all-upper", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is \u0062\u00F4\u006E

    // Unicode escape all chars using \u{HHHH}
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-all-curly-upper", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is \u{0062}\u{00F4}\u{006E}

    // Unicode escape 8bit chars using HTML hex &#xH;
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-8bit-html-hex", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is bôn

    // Unicode escape all chars using HTML decimal &#D;
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-all-html-dec", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is bôn

    // Unicode escape all chars using u+HHHH
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-all-plus", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is u+0062u+00f4u+006e

    // Unicode escape 8bit chars using angled brackets <HHHH>
    success = sb.setString(value: str)
    sb.encode(encoding: "unicode-escape-8bit-angle-upper", charset: charset)
    print("\(sb.getAsString()!)")
    // Output is b<00F4>n
