Android สอบถามเรื่อง WebView ครับ ของผมไม่แสดงภาษาไทยครับ เกิดจากอะไรครับ

public class ActivityForm2 extends Activity  {
	
	WebView mWebView;
	@SuppressLint("SetJavaScriptEnabled")
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_form2);
		
		mWebView = (WebView) findViewById(R.id.webview2);
		mWebView.getSettings().setBuiltInZoomControls(true);
		mWebView.getSettings().setSupportZoom(true); 
		mWebView.getSettings().setUseWideViewPort(true);
		mWebView.getSettings().setLoadWithOverviewMode(true);
		mWebView.setWebViewClient(new HelloWebViewClient());		
		mWebView.getSettings().setJavaScriptEnabled(true);
		mWebView.loadUrl("http://reg.reru.ac.th/utility/exam-schedule-control.asp");		
	}

		@Override
		public boolean onKeyDown(int keyCode, KeyEvent event) {
			if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
				mWebView.goBack();
				return true;
			}
			return super.onKeyDown(keyCode, event);
		}

		private class HelloWebViewClient extends WebViewClient {
			private static final String TAG = "HelloWebViewClient";;

			// Give application a chance to catch additional URL loading requests
			
			@Override
			public boolean shouldOverrideUrlLoading(WebView view, String url) {
				Log.i(TAG, "About to load:" + url);
				view.loadUrl(url);
				return true;
			}
		}
