Why is resourceBundle output with strange symbols?

Question

I try to internazionalize my web app and use Locale and ResourceBundle:

Locale locale = new Locale(language);
ResourceBundle messages = ResourceBundle.getBundle("i18n.messages", locale);
try {
    String message = messages.getString(key);
    pageContext.getOut().write(message);
} catch (IOException e) {
    e.printStackTrace();
}

As a result the output is "Ôîðìà óïðàâëåíèÿ äëÿ àäìèíà". I don`t know what to do, please, help
