1. Go to Control Panel > Web Content
2. Start adding a Basic Web Content and go to the Schedule section
3. Insert "/hu" to the URL after the hostname in your browser so that the language changes to Hungarian
4. Click on one of the date selectors
5. The short name of the weekdays don't show up properly. The symptom is similar with e.g. "/ro" Romanian locale

The root cause is we are slicing the last character of the short weekday even if it's only one character.
