    ; the original string in binary form and $sConverted will hold the result
    ; afte it's been transformed back to the original format.

    ; Convert the ANSI compatible binary string back into a string.
    $sConverted = BinaryToString($sBinary)

    ; Display the resulsts.  Note that the last two characters will appear
    ; as ?? since they cannot be represented in ANSI.
