"Unicode Demystified" seems to say that "Unicode scalar value" is
obsolete terminology on page 80, and also implies that this term is
synonymous with "code point."  Is it wrong?  (I'm unclear on whether
surrogates are code points or not, but am even less clear whether that
difference matters in a context where chars are code points.)
