This means that ideally, if the window is not a unicode window, then there
should be no A->W->A translation.
Since there is no way of knowing if the target window uses the same
code page, or even if its code page won't change between the time the
message is stored in the queue and when it is retrieved, the only sane
approach is to store messages in the queue in Unicode. Only
SendMessage calls that bypass the queue avoid the translation. I'm
pretty sure that this is what Windows does too, if you have a test
demonstrating the opposite I'd be very interested to see it.
