http://cgit.freedesktop.org/xorg/lib/libX11/commit/nls/en_US.UTF-8/Compose. pre?id=9b8d8c9e5b27273e8856a3851ba9b68022bed3cd
OK, thank you for the link and then we need to fix en_US.UTF-8. ibus en_US.UTF-8 was copied from GTK+ one and it seems it's old.
Now I created the patch of en_US.UTF-8 and fi_FI.UTF-8 but others are not yet.
I'm a bit tired to convert the data and probably it's better to fix this in post f20 since the change is big and the f20 beta is coming. Probably it's also better for me to fix the fi problem when running apps with GTK_IM_MODULE=gtk-im-context-simple .
