As per the overview, code unit is defined as "an indivisible unit of an encoded unicode scalar value". While individual 8-bit, 16-bit or 32-bit code units are indivisible bit combinations, individual units do not represent scalar values. In 16-bit strings for example, a surrogate pair is a divisible combination of two indivisible code units, both surrogates, that are not scalar values. In 8-bit strings, individual code units map to neither scalar values nor code points.
As per Unicode, Glossary:
Suggesting to basically copy Unicode's definition and drop the reference to scalar values.
