Running virt-viewer-x64-0.5.6.msi, on Windows 7, connecting to QEMU using
spice, AltGR key combinations fails (using Swedish keyboard layout both at
server and client).

I suspect that this is a variant of
https://bugzilla.redhat.com/show_bug.cgi?id=904092.

After some debugging, I realized that there is an extra VK_LCONTROL
keypress sent by Windows. This extra VK_LCONTROL will then make the key
e.g. AltGr-< actually be Control-AltGr-<, which is not interpreted as a |
sign.

So in spice-widget.c : keyboard_hook_cb(), I added SPICE_DEBUG lines which
printed out the hooked->scanCode, and realized that this extra VK_LCONTROL
has a very suspect scanCode with bit 9 set. If I instead press the left
Ctrl key, it will also emit VK_LCONTROL, but with bit 9 cleared.

So I just made sure that keyboard_hook_cb(), silently dropped these strange
VK_LCONTROL events, which seems to work for me.
