golang转换包含unicode的字节数组

type MyStruct struct {
    Value json.RawMessage `json:"value"`
}

var resp *http.Response

if resp, err = http.DefaultClient.Do(req); err == nil {
    if resp.StatusCode == 200 {
        var buffer []byte
        if buffer, err = ioutil.ReadAll(resp.Body); err == nil {

            mystruct = &MyStruct{}
            err = json.Unmarshal(buffer, mystruct)

        }
    }
}

fmt.Println(string(mystruct.Value))

it produces something like:

   \u003Chead>
  \u003C/head>
  \u003Cbody>

Doc at: http://golang.org/pkg/encoding/json/#Unmarshal

says: When unmarshaling quoted strings, invalid UTF-8 or invalid UTF-16 surrogate pairs are not treated as an error. Instead, they are replaced by the Unicode replacement character U+FFFD.

I kinda think this is what is going on. I just can't see the answer as my experience with go is minimal and I'm tired.

    You decided to use json.RawMessage to prevent parsing of the value with key value in your json message.

    The string literal "\u003chtml\u003e" is a valid json representation of "<html>".

    Since you told json.Unmarshal not to parse this part, it does not parse it and returns it to you as-is.

    If you want to have it parsed into an UTF-8 string, then change the definition of MyStruct to:

    type MyStruct struct {
    Value string `json:"value"`
}
