The thing is that we are trying to create a VM where the internal
representation of the characters will be Unicode.
This means that the VM we use is sending unicode charcodes to the image, we
use unicode fonts etc...
So, a UTF interpreted string will not display properly in our image. Unless,
we use interpreters for our Unicode chars...
I think we will have to patch the VM again so that the clipboard related
methods send again unicode streams to the image.
Don't know which solution of the two is more desirable...

The related methods that are called when putting to or getting something
from the clipboard are
    int clipboardSize(void)
    int clipboardWriteFromAt(int count, int byteArrayIndex, int startIndex)
    int clipboardReadIntoAt(int count, int byteArrayIndex, int startIndex)

in
    sqWin32Window.c

Any help on that Diomidis?
