Problem when using Cyrillic

Hello,

Use AutoItX v3.1.0
running the simliest vb script:

'-------------begin-----------
oShell.Run "notepad.exe", 1, FALSE
oAutoIt.WinWaitActive "Untitled - Notepad", ""
oAutoIt.Send "Hello, World{ENTER}"
oAutoIt.Send "Çäðàâñòâóé, Ìèð" ' it is "Hello, World", only in Russian :-)
'-------------end-------------

After it in the second row of Notepad I see abracadabra. I guess it is the
problem of encoding.
Is it possible to fix the problem somehow?

P.S. The same problem when using Cyrillic in: StatusbarGetText, WinGetText,
WinWait
