If we create multi language program app, we externalize strings in property file.
now this file is in format:
javax.faces.component.UIInput.REQUIRED=\u041C\u043E\u043B\u044F \u0432\u044A\u0432\u0435\u0434\u0435\u0442\u0435 \u0437\u0430\u0434\u044A\u043B\u0436\u0442\u0435\u043B\u043D\u0438\u0442\u0435 \u043F\u043E\u043B\u0435\u0442\u0430!
It will be difficult for translator to translate this.
May be export in simple txt format will be more useful.
