HttpEntity 响应中的字符呈现不正确

Question

我正在做一个小应用程序，它接收一些带有 UTF-8 编码的 XML，浏览器中的相同 XML 可以正确呈现字符，而在 Android 中我有一些“垃圾”，例如。 WÅochy 代替 Włochy 或 Dwójka 代替 Dwójka。显然我做错了什么，有人可以帮我解决吗？

以下

String response = EntityUtils.toString( resEntity ).trim();
Log.i( CLASS_NAME, "RESPONSE=" + response );
//This returns response with incorrectly rendered characters eg. WÅochy instead of Włochy

是发送 POST 请求并接收响应的代码，它在 AsyncTask 中运行：

protected Document doInBackground(ServiceQuery... queries)
{
    if ( m_sGateway == null ) return null;

    Document result = null;

    try
    {
        HttpClient client = new DefaultHttpClient();

        HttpPost post = new HttpPost( m_sGateway );

        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add( new BasicNameValuePair( "mdsXML", queries[0].getQueryString() ) );

        UrlEncodedFormEntity ent = new UrlEncodedFormEntity( params, HTTP.UTF_8 );
        post.setEntity( ent );
        HttpResponse responsePOST = client.execute( post );

        HttpEntity resEntity = responsePOST.getEntity();

        if ( resEntity != null )
        {
            Log.i( CLASS_NAME, "contentLength:" + resEntity.getContentLength() );
            Log.i( CLASS_NAME, "getContentEncoding():" + resEntity.getContentEncoding() );
            Log.i( CLASS_NAME, "getContentEncoding().isChunked():" + resEntity.isChunked() );
            Log.i( CLASS_NAME, "getContentEncoding().isRepeatable():" + resEntity.isRepeatable() );

            String response = EntityUtils.toString( resEntity ).trim();

            Log.i( CLASS_NAME, "RESPONSE=" + response );//This returns response with incorrectly rendered characters eg. WÅochy instead of Włochy


            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();

            InputStream is = new ByteArrayInputStream( response.getBytes(HTTP.UTF_8) );


            result = db.parse( is );
            result.getDocumentElement().normalize();
        }

    }
    catch (Exception e)
    {
        e.printStackTrace();
        Log.e( CLASS_NAME, "doInBackground error." );
        result = null;
    }

    return result;
}

Paul Grime 为我的问题提供了答案。

import org.apache.http.util.EntityUtils;

String response = EntityUtils.toString( resEntity, HTTP.UTF_8 );

其中 resEntity 是 HttpEntity 实例。
