Both Guacamole and VNC use X11 keysyms to represent key events. These keysyms are independent of keyboard layout, and represent the actual identity of the key pressed. Because QEMU needs to emulate the hardware of the keyboard, it will internally need to translate those keysyms back into scancodes, thus removing the identity of the key pressed. The information reaching the OS running beneath QEMU describes nothing more than the location of the key on the keyboard, and the OS will re-interpret that according to the keyboard layout it's configured to use. There is likely a way to inform QEMU of the keyboard layout of the guest OS, allowing that mapping process to work correctly, but you will still be limited by the keys defined by the layout of the guest OS. You won't be able to type characters which are not present in that keyboard layout. If you instead run a native VNC server within the guest OS itself, there won't be that intervening keysym -> scancode layer, and things should work as expected. - Mike
