A simple testcase

I did WINEDEBUG=+relay wine idag.exe > relay.log 2>&1 and found this
0009:Call user32.VkKeyScanA(00000023) ret=00442274
0009:Ret  user32.VkKeyScanA() retval=0000ffff ret=00442274
<blabla>
0009:Call user32.DrawTextA(000005cc,00c75594 "Keyboard layout error:\nFailed to
get the scan code of '#'\n(VkKeyScan failure)",0000004d,0032d2cd,00000440)
ret=400c8610

So VkKeyScanA('#') fails as described in the message.

Compiling the testcase on windows (XP, cygwin, gcc) gives
VkKeyScanA('#') :: 1587

IsDBCSLeadByte('#') :: 0
cChar #  Wchar #
VkKeyScanExW() :: 1587

and on my system (KUbuntu, winegcc) :
VkKeyScanA('#') :: -1

IsDBCSLeadByte('#') :: 0
cChar #  Wchar #
VkKeyScanExW() :: 65535

So USER_Driver->pVkKeyScanEx(cChar, dwhkl) fails.
