What Claude mentioned is already part of the specification: "Input is a List consisting of all of the characters" and "Each character is either a code unit or a code point, depending upon the kind of pattern involved" (21.2.2.1). But I added the Note section to the page of my proposal for clarification two days ago because I was asked a similar question. Incidentally, in the initial version of the proposal I used the term "code point" but later changed it to "character" since Allen pointed out: https://mail.mozilla.org/pipermail/es-discuss/2015-May/042922.html
