Thank you, Edward, that helped me out a lot. :)
My code now looks like this (to simplify this for the moment, I sticked 
to the non-unicode variant):
---------------------------------
#Encoding: UTF-8
require "win32/api"
GetLastError = Win32::API.new("GetLastError", '', 'I', "kernel32")
SendInput = Win32::API.new("SendInput", 'IPI', 'I', "user32")
#Needed for the KEYBDINPUT struct's last parameter
GetMessageExtraInfo = Win32::API.new("GetMessageExtraInfo", '', 'P', 
"user32")
INPUT_KEYBOARD = 1
KEY_A = 0x41
#KEYEVENTF_UNICODE = 0x0004

input = [
  INPUT_KEYBOARD,
  KEY_A,
  0,
  0,
  0,
  GetMessageExtraInfo.call
].pack('issiiP')

#While the program pauses, I click into an editor window
#to see wheather I get the 'a' or not.
sleep 3

SendInput.call(1, input, input.size)
p GetLastError.call
---------------------------------
I'm using Ruby 1.9.1-p243 at the moment (will update to -p376 soon), but 
I've checked that Array#pack returns a BINARY-encoded string, so there 
shouldn't occur a problem. Nevertheless, I get error code 87, what means 
"One of the parameters was invalid.". I suppose it's the C array I don't 
provide, even if it contains only one element. Do you know how to build 
up one?
