The use of it for CRLF might be different, but I'm not sure the concept is.
Indeed, according to <http://www.unicode.org/reports/tr29/>:

"One or more Unicode characters may make up what the user thinks of as a
character or basic unit of the language. To avoid ambiguity with the
computer use of the term character, this is called a grapheme cluster. For
example, ³G² + acute-accent is a grapheme cluster: it is thought of as a
single character by users, yet is actually represented by two Unicode code
points."

Indeed. But from the above:

"In those relatively rare circumstances where programmers need to supply end
users with character counts, the counts should correspond to the number of
segments delimited by grapheme cluster boundaries."

In the light of that, I'm not sure what else AS could do.
