java - 带有 StringEntity 的 HttpPost 具有特殊字符，如 ®，看到 ¿½` 而不是 ®

Question

我需要为 stringentity 使用特殊字符，如下所示。

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpEntity entity = new StringEntity("test®");
httpPost.setEntity(entity);
httpPost.setHeader("Accept-Encoding", "UTF-8");

HttpResponse response = httpClient.execute(httpPost);
BufferedReader reader =  new BufferedReader(new InputStreamReader((response.getEntity().getContent())));
while ((reader.readLine()) != null) {
    System.out.println (reader.readLine());
}
reader.close();

输出在响应中包含 test� 而不是 test®。

Answer 1

更改为:

    HttpEntity entity = new StringEntity("test®", "UTF-8");
