    According to the new 4.0 definitions:

    - code points go from 0..10FFFF, inclusive
    - "scalar value" == "non-surrogate code point", so they are simply a
    restriction of code points to the ranges 0..D7FF, E000..10FFFF

    Since surrogate code points can never represent characters, for a given
    character you can refer to "its code point" or to "its scalar value"; in
    that circumstance there is no effective difference in the terms.
