    Code point

        If you imagine Unicode as a mapping from integers to
        characters, each integer is a code point. In other words
        a code point is an integer between 0 and TOPCHAR.
        Some code points are really mapped to characters. Some will 
        someday be used for characters. Some are guaranteed never 
        to be used for characters.
