That seems a bit implausible. Can you confirm that with an experiment?

First, capture the output of the following Python code

    s = "“±”"
    print("".join(chr(b) for b in s.encode()))

directly into an Emacs buffer. It should look like

    â\200\234±â\200\235

except that each backslash-octal sequence is a single character. Then
try using the decode-coding-string function on that string, and see if
you get the original text (the value of the s variable in the Python
code) back.

When I try it in GNU Emacs, I don’t. It just returns the string
unchanged.
