Sure, CGEventCreateKeyboardEvent was the first obvious way (and probably the one I'll stick with).

Just be warned that the codes are different for each keyboard layout, so already the stock code

CGEventRef event1, event2, event3, event4;
event1 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, true);
event2 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)6, true);
event3 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)6, false);
event4 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, false);

will produce varying results - "Z" on English QUERTY keyboards, "Y" on German QUERTZ ones. Given many many different layouts it is at least not trivial to get the characters / strings you need...
