I'm learning Java, and while writing my first web app, I've encountered some problems with Polish letters (like ą, ć, ł, ś etc.). Problem is that when I bind the object to a form in GET request, it shows ok in browser, with all Polish letters just fine (database is configured properly), but after hitting Send button on the page in my controller, in POST request, I get garbled text with Polish letters missing. When I set encoding in the view (JSP file) to utf-8 in controller instead of 'ą' I get 'Ä' (two bytes) and with encoding set to iso8895-2 I get '±' (1 byte). With servlets the solution was to add
request.setCharacterEncoding("8859_2");
as the first line in POST request, but Hibernate doesn't use HttpServletRequest, so even when I add it, I still get garbage. STS (my IDE) is set to UTF-8.
Is there any solution to his?

Problem was solved by setting up filter and reconfiguring Tomcat a bit, described here: https://stackoverflow.com/a/40484064/8783698
