Http: the response body become garbage if include Chinese chars in the response body

[xiyulangzi]

I use Flutter 1.0 latest http package, the code get info from my REST API, it get some data from DB.
when some field contain chinese chars, the response body become garbage,
but if I use Postman to test the REST API, the data in response body is correct.

    var response = await http.post(
      constAWSAPIGateway_getProductByUser[CONST_API_STAGE],
      headers: {
        'Content-Type' : 'application/json; charset=utf-8',
      },
      body: json.encode(postBody),
      encoding: Utf8Codec() //this line doesn't make difference
    );

in postman response is correct:
{\"pid\":11,\"name\":\"家具坠子1\"}

in Flutter and your http package:
{"pid":11,"name":"å®¶å…·å å­1"}

I try play around with the UTF8 setting but doesn't help.
so would you please look into this issue. or suggest kind of woraround?

thanks in advance.

after some search, found the reason as application/json default is utf-8 but missing the charset=utf-8 confused http package which treat as latin1.

my workaround is below:
//var responseJson = jsonDecode(response.body);
=>
var responseJson = json.decode(utf8.decode(response.bodyBytes));

then Chinese chars can display correctly. hope this help.

http might need add some handling for json.
