org.json字符编码/解码问题

Question

So I have a webservice call that is giving me back a JSON string. I've requested that the response send be back the content in UTF-8 encoding. When I inspect the value returned everything looks good. It's when I create a new JSONObject and pass the JSON text into the constructor that things start to cause problems.

Specifically: The webservice returns with an EM DASH (http://www.fileformat.info/info/unicode/char/2014/index.htm) character in the response - "format":"On Demand Event—All Sessions"

After the JSONObject receives the string it converts this character into the java representation of this character - "format":"On Demand Event\—All Sessions"

I am using the org.json library to do my bidding and am considering moving to a different implementation if necessary. Here is what I've got running the show:

HttpClient client = new HttpClient();
GetMethod getDownloads = new GetMethod("http://localhost:8080/ecommerce-ws/service/account/downloads");

getDownloads.getParams().setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "UTF-8");
getDownloads.setRequestHeader("Accept", "application/json");

client.executeMethod(getDownloads);

String httpResponse = getDownloads.getResponseBodyAsString();

JSONObject downloadsJSON = new JSONObject(httpResponse);

Is there some way that I can set the character encoding on the JSONObject when it parses the string? I've done quite a bit of looking around and have found very little that helps.

Thank you in advance for your assistance.

Good question.

The JSON spec seems to allow escaping of all unicode chars

http://www.ietf.org/rfc/rfc4627.txt

but when I test, the GSON doesn't seem to escape the EM DASH
