Ok, then maybe we should have TranslateMessage not call that, and use
something else instead? This is particularly prominent from this
sentence in the ToUnicodeEx documentation
(http://msdn2.microsoft.com/en-us/library/ms646322.aspx):

Maybe I don't understand the code well enough, but it seems to me that
we report on the dead-key press, but not translate the following
character. Is that correct?
