Those bytes are the utf-8 encoding of those CJK ideograph (I won't even
pretend to know what those CJK ideographs are or what they mean).

Those bytes are the gbk encoding of those CJK ideographs.

Those are the "code points" of those characters. Unicode assigns code
point, which are just integers, to characters. The code points are easier
to work with inside your application, but you usually have to encode them
into bytes to transfer them into or out of your application.
