winex11.drv: Transmit WM_DEADCHAR messages to applications

But it doesn’t work that way under Windows. Shouldn’t Wine try to stick
to Windows behavior as close as possible ?

I’m sorry but I fail to see any incompatibility between the two
alternatives. Wine can generate WM_DEADCHAR messages AND let X/input
method handle the real processing (and the generation of the final
event) ; this patch never skip the XFilterEvent call, so it’s still up
to your favorite IM to generate the final char from the keystrokes
sequence.

Are you speaking about XCompose or things like ibus ? Both still looks
like OK with this patch (tested with wine’s notepad, ibus-anthy and
XCompose keys from http://bepo.fr/).
