Java android将utf8内容发送到servlet

我使用Android将英语和阿拉伯语内容发送到Servlet，但数据会随文件一起发送到服务器。如何解决？以下是我在Android中的代码：

StringEntity se = new StringEntity(gsonString);
se.setContentType("text/json;charset=UTF-8");
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,
"application/json;charset=UTF-8"));
HttpPost httpRequest = new HttpPost(methodURL);
httpRequest.setEntity(se);
HttpResponse response = httpClient.execute(httpRequest,localContext);

Servlet代码

request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
BufferedReader in = new BufferedReader(new InputStreamReader(request.getInputStream()));
    String line = in.readLine();
    String gsonString = line;
    while (line != null) {
        gsonString += line;
        line = in.readLine();
    }

有什么建议吗？

使用这些方法

HttpPost httpPost = new HttpPost(method_url);

StringEntity postEntity = new StringEntity(HTTP.UTF_8);
httpPost.setEntity(postEntity)

或

使用这些方法

HttpPost httpPost = new HttpPost(method_url);

StringEntity postEntity = new StringEntity(HTTP.UTF_8);
httpPost.setEntity(postEntity)

或

您是否尝试过使用UTF8格式创建StringEntity，我在代码中的意思是：StringEntity se=new StringEntity（gsonString，“UTF-8”）；为什么要将字符编码设置为

request.setCharacterEncoding（“UTF-16”）尝试
UTF-8
关于StringEntity se=新的StringEntity（gsonString，“UTF-8”）；服务器遇到的相同问题？？？？？关于UTF-16，我之前尝试过插入数据库中的UTF-8？？？？然后我使用了utf-16 it Works。您是否尝试过使用UTF8格式创建StringEntity，我的意思是在代码中类似这样的内容：StringEntity se=new StringEntity（gsonString，“utf-8”）；为什么要将字符编码设置为
