--- Comment #23 from Karol Herbst wine@karolherbst.de --- Yeah, the wine trace is too verbose for me and I wanted a clear list of function entries.
I was thinking about simulating two key presses and check what X11 is doing out of it. I don't found any way how to get the current dead-key state out of the X server, so I already thought about such an approach, too.
It won't be perfect, but I guess this should be better than the current state.
