GsonDecoder, JacksonIteratorDecoder and Jackson3IteratorDecoder read the response body with asReader(UTF_8), ignoring response.charset(). A non-UTF-8 charset declared on the response (e.g. charset=ISO-8859-1) is mis-decoded to U+FFFD. The sibling JSON decoders all pass response.charset(); do the same here.

Repro: a server response with
Content-Type: application/json; charset=ISO-8859-1and anISO-8859-1encoded body decoded throughGsonDecoder,JacksonIteratorDecoderorJackson3IteratorDecoder.Cause: those three read the body with
asReader(UTF_8), droppingresponse.charset(), so non-ASCII bytes come back asU+FFFD. The siblingJacksonDecoder,Jackson3Decoder,Fastjson2Decoder,JacksonJrDecoderandJsonDecoderalready passresponse.charset().Fix: pass
response.charset()in the three decoders, matching the siblings.response.charset()already defaults to UTF-8, so plain UTF-8 responses are unchanged. Regression test added per module.
