Isn't it? It sure looks like a sequence of length-1 (sub)strings to me.
Of course, strings can also be views as a sequence of paragraphs, lines,
words, or any other sort of substring you like. Hypertalk allowed you to
read strings in arbitrarily nested "chunks":
get the last character of the first word of the third line of text
with similar syntax for writing and iteration. One might argue that
there's nothing particularly useful about characters, and treating
strings as sequences of words, lines etc could be more useful. But I
don't think we can argue that strings aren't sequences of
substrings, including characters.

They certainly aren't members (attributes). You can't access a
particular substring using dot notation:
# Give me the first char in the string
c = string.0 # Syntax error.
So substrings aren't attributes/members. What would you name them? The
same applies to lists and other sequences as well.
