[Pharo-project] Keyboard events issue on Mac VM

If you press the key "a", you`ll get

#(2 2534082 0 1 0 0 0 1)
#(2 2534082 97 0 0 97 0 1)
#(2 2534157 0 2 0 0 0 1)

from the virtual machine. For "A":

#(2 2536225 0 1 1 0 0 1)
#(2 2536225 65 0 1 65 0 1)
#(2 2536413 0 2 8 0 0 1)

The only event with the information about pressed character is
keyStroke (the fourth value is 0) so you will not know the resultant
character because MacRoman charCode and/or utf32Code is missing (they
are present on Linux). It is printed from
InputEventFetcher>>signalEvent:. Am I missing something?
