Actually you never count scalar values. You are confusing tham with code
units. Twitter was orignally counting UTF-16 code units, but now counts
code points.

Scalar values are unrelated, they are properites assigned to code points so
that all code points have a scalar value but the reverse is true only with
the valid range 0 to 0x1FFFFF. Scalar values are only used if you need to
perform arithmetic to compute code points from others. This genreally does
not work well within the UCS except in a few very small ranges (like
decimal digits). The scalar value is also needed to convert from one
standard UTF to another.
