Question

我正在Android中开发一个应用程序，我可以插入新的评论（比如在facebook或任何其他社交网络中）。

执行此操作的功能如下：

public static String putNewComment(String comment, int userId, int trackId) throws IOException,JSONException {

    HttpPost post = new HttpPost(Globals.PUBLISH_NEW_COMMENT);

    StringEntity input = new StringEntity("{\"comment\": \""+comment+"\",\"trackId\":"+trackId+",\"userId\":"+userId+"}");
    input.setContentType("application/json;charset=UTF-8");
    post.setEntity(input);
    input.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
    post.setHeader("Accept", "application/json");
    post.setEntity(input);

    HttpResponse response = client.execute(post,Globals.localContext);
    System.out.println("Response Code : "
            + response.getStatusLine().getStatusCode());

    BufferedReader rd = new BufferedReader(
            new InputStreamReader(response.getEntity().getContent()));

    String resultMy="";
    String line;
    while ((line = rd.readLine()) != null) {
        resultMy+=line;
        System.out.println("Server says: "+line);
    }

    return resultMy;

}

每当我尝试添加包含é，ò等几个unicode字符的新评论时，我都会收到此错误：

com.fasterxml.jackson.databind.JsonMappingException：无效的UTF-8中间字节0x22

现在，我知道这个错误是因为内容编码是UTF-8而我正在尝试插入一个unicode字符。问题是如何解决这个问题？我尝试通过这种方式改变：

input.setContentType("application/json;charset=UTF-16");
    post.setEntity(input);
    input.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-16"));

或

input.setContentType("application/json;charset=UTF-32");
    post.setEntity(input);
    input.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-32"));

但它不起作用！请帮帮我
