[Spice-devel] [spice-gtk v4 3/3] Send Hangul key in KR keyboard

[Frediano Ziglio]

From: Takao Fujiwara <tfujiwar at redhat.com>

Korean keyboard assigns Hangul key on the position of Right Alt and
Left Alt and Hangul keys have the different scancodes but MapVirtualKey()
returned the same scancode and could not use Hangul key on Linux desktop.

The fix is to send the right scancode of VK_HANGUL.
