Input.GetKey() does not log symbols when using a Japanese keyboard

As Designed

Unity input system key codes and input manager key codes are designed with game controls in mind, that means pressing the same location on a keyboard should result in the same action regardless of what is printed on a key or what current system language is set. Unity relies on physical hardware in the keyboards to report same USB HID "usage" for the keys in the same location. There is a practical limit what could be achieved here as different keyboards might report different data, and this is outside of Unity control. When trying to use key codes for text input this is a wrong tool to do that. Instead `Keyboard.current.onTextInput` callback should be used, this will provide actual text characters that are printed on a keyboard keys based on current system language layout. When trying to use key codes for shortcuts it will not be as trivial, as neither key code or display name is sufficient to provide natively feeling shortcuts, please refer to Visual Studio Code wiki for more information how to implement natively feeling shortcuts https://github.com/microsoft/vscode/wiki/Keybinding-Issues#how-it-works-on-windows
