I had english version of Windows 7 which was upgraded to Windows 10. After installation I decided to install Polish language pack and I can use Polish characters in terminal or text editors. On the other hand I have two applications: console application I connect to via VPN and window application installed on local machine. In both cases when I try to write text I can't use Polish characters (I see different letters or characters that doesn't belong to Polish alphabet) but I can see Polish characters in menu of the window application. Console application doesn't show Polish characters on menu from the beginning. These are two different applications with no connection whatsoever. I have no problem using them on Polish version of Windows 7.
Can you suggest any solution to this problem?
