Android HTTP Response with different language characters

Question

I am working on basic HTTP request response example in Android. For this example project, I tried to work with Google Translate URL. However, the characters of other languages are replaced by junk or hex values in the response. If I hit the URL from desktop browser, it works fine.

Here is the code:

httpClient = new DefaultHttpClient();
httpGet = new HttpGet("https://translate.google.com/m?hl=en&sl=en&tl=gu&
    ie=UTF-8&prev=_m&q=sample") ;
httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity() ;
responseString = EntityUtils.toString( httpEntity, HTTP.UTF_8 );
// http response is all good except the characters that are in different 
// language are replaced by hex or junk characters. 

What am I doing wrong? Any help?
