void ChilkatSample(void)
    {
    bool success = false;

    //  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.
    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";
    }
