No: the "\xBA" string does not contain any character, it only contains
bytes (we call such "string of bytes" a "unibyte string" and the usual
"string of characters" is called a "multibyte string").

And yes, the (integer) codes of the bytes of "\xBA" happen to be
identical to the (integer) codes of the characters of (concat '(#xBA)).

So (equal (append "\xBA" nil) (append "º" nil)) is non-nil.
Note that the same applies to: (equal (append "\xBA" nil) (append [#xBA] nil))
