URLEncodedUtils.parse(HttpEntity) not working if Content-Encoding is not specified
----------------------------------------------------------------------------------

                 Key: HTTPCLIENT-1175
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1175
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.2 Beta1, 4.1.3
            Reporter: Hendy Irawan


The code below does not work :

	/**
	 * Sets the authCode received from Facebook and exchanges it with the access token.
	 * @param authCode
	 * @throws IOException 
	 * @throws ClientProtocolException 
	 */
	public void setFacebookAuthCode(String authCode) throws ClientProtocolException, IOException
{
		log.info("Retrieving access token using authCode {}", authCode);
		URI accessTokenUri = facebookAuth.getAccessTokenUri(authCode);
		DefaultHttpClient client = new DefaultHttpClient();
		HttpGet accessTokenReq = new HttpGet(accessTokenUri);
		HttpResponse response = client.execute(accessTokenReq);
		if (response.getStatusLine().getStatusCode() != 200)
			throw new IOException(String.format("GET %s throws HTTP Error %d: %s",
					accessTokenUri, response.getStatusLine().getStatusCode(), response.getStatusLine().getReasonPhrase()));
		// Probably due to non-existing Content-Encoding, this one is not working:
		List<NameValuePair> data = URLEncodedUtils.parse(response.getEntity());
		setFbAccessToken(data.get(0).getValue());
		
		log.info("Access token received, redirecting to Post Status page");
		ExternalContext external = FacesContext.getCurrentInstance().getExternalContext();
		external.redirect(external.encodeActionURL("/faces/post.xhtml"));
	}

I have to use a workaround :

		String body = IOUtils.toString( response.getEntity().getContent() );
		Scanner scanner = new Scanner(response.getEntity().getContent());
		ArrayList<NameValuePair> data = new ArrayList<NameValuePair>();
		URLEncodedUtils.parse(data, scanner, "UTF-8");

Expected behavior :

Should either default to UTF-8 (recommended) or make it an explicit parameter.
