    // First demonstrate encoding strings to ascii85 and back.
    sb := chilkat.NewStringBuilder()

    success := sb.Append("Man is distinguished, not only by his reason, but by this singular passion from other animals, which is a lust of the mind, that by a perseverance of delight in the continued and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.")

    encodedAscii85 := sb.GetEncoded("ascii85","utf-8")
    fmt.Println(*encodedAscii85)

    // Result is: 9jqo^BlbD-BleB1DJ+*+F(f,q/0JhKF<GL>Cj@.4 ... DII?(E,9)oF*2M7/c

    // Decode back to the original:
    sb.Clear()
    sb.Append(*encodedAscii85)
    success = sb.Decode("ascii85","utf-8")
    fmt.Println("Original:")
    fmt.Println(*sb.GetAsString())

    // ---- Now encode binary data to ascii85 ----
    bd := chilkat.NewBinData()
    success = bd.LoadFile("qa_data/jpg/starfish20.jpg")
