    // 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
    glob = CkGlobal_Create();
    CkGlobal_putDefaultUtf8(glob,TRUE);

    sb = CkStringBuilder_Create();

    // Here we wish to URL decode the following string:
    success = CkStringBuilder_Append(sb,"%D7%9E%D7%95%D7%A6%D7%A81.jpg");

    // 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 = CkStringBuilder_Decode(sb,"url","utf-8");

    // sb now contains the decoded string.
    printf("%s\n",CkStringBuilder_getAsString(sb));


    CkGlobal_Dispose(glob);
