= "or count code points corresponding to UTF-16 code units"; those
happen to be BMP code points.

Twitter has been claiming since /at least/ April 2012 that they're
counting "code points" ("counts the number of codepoints" in their
article). (I know it goes back further, but I'm too lazy to trace
things.) André observed just in October 2012 that they were actually
counting UTF-16 code points (though more accurate to call them UTF-16
code units, which all match up with BMP code points, which is what I
think Doug meant, but it's a terminological detail, and this confusion
actually turns out to be part of the problem). You are relegating scalar
values to lower status (factually wrong; see everywhere in the
glossary). Now what on earth do they mean by "codepoint" [spelled as such]?

If you really want, you can say that Twitter wasn't confusing code
points [typecast from UTF-16 code units, in my worldview] with scalar
values but instead code points [in the "scalar value" sense] with code
units, but that's terminological sophistry. Under either view they
didn't know what they were doing when handling "code points", however
defined or interpreted.
