You’d think decode-coding-string would achieve the same result,
operating directly on the string value
<https://www.gnu.org/software/emacs/manual/html_node/elisp/Explicit-Encoding.html>;
but it doesn’t. Buffers can be set to multibyte/unibyte mode, but
strings cannot.

Python has separate “string” and “bytes” types precisely to get around
problems like this; Emacs, it seems, does not.
