    {
    // Note: We'll want to tell Chilkat that we're passing in utf-8 strings, and we wish to receive utf-8 "const char *" strings.
    // See Global utf-8
    CkGlobal glob;
    glob.put_DefaultUtf8(true);

    CkStringBuilder sb;

    // Append the hex.  The hex can be uppercase hex or lowercase hex, it doesn't matter.
    bool success = sb.Append("D79ED795D7A6D7A8");

    // Notice the above string contains Hebrew chars using the utf-8 byte representation.
    // See https://www.loc.gov/marc/specifications/codetables/BasicHebrew.html
    // For example:  D79E is the HEBREW LETTER MEM

    // Therefore, when we decode to binary bytes, we must interpret the bytes as utf-8
    // to get characters.

    // Tell Chilkat to URL decode like this:
    success = sb.Decode("hex","utf-8");

    // sb now contains the decoded string.
    std::cout << sb.getAsString() << "\r\n";
