quoted-printable-decode-region gives you a byte string. You are then
supposed to decode that into text using whichever character encoding
you know is used. (Quoted-printable encoding, unlike URL
percent-encoding, does not mandate UTF-8. In RFC 2822 mail, the
character encoding will be given in the Content-Type header’s charset=
parameter. =C3=AD looks like a quoted-printable encoding of UTF-8
encoding of the character U+00ED LATIN SMALL LETTER I WITH ACUTE.)

As a shortcut, you could pass the character encoding as the last
argument to q-p-d-r, but that is described as deprecated in the
docstring.
