Keyboard handling, compose key broken in Trinity nightlies

Hi Tim and others, Is there significant development going on regarding keyboard handling or maybe character handling? I'm a bit surprised, because I didn't know this depended on the toolkit, but with the current nightlies, I'm unable to use my compose key to compose characters in any Trinity application. In Qt4 and GTK applications (within Trinity), the compose key works correctly. In the past, this worked without issues in Trinity as well. I can imagine this is not noticed by everybody quickly, I myself need to use compose a lot to type in foreign languages. Let me know if I can help with reproducing/solving this. Best regards, Julius
