   @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_german);
        TextView abc = (TextView) findViewById(R.id.abc);
        String chararc = getString(R.string.german);
        try {
            final String s = new String(chararc.getBytes(), "UTF-8");
            abc.setText(s);
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
