I verify that this bug exists. What happens is that Xorg is able to send the mentioned characters, however, somewhere in both GTK+ and QT applications cannot receive them.
To verify, run an X application such as "xterm" (is there an old-style X editor around?). Try $ xterm -font "-bitstream-dejavu sans mono-medium-r-normal--0-0-0-0-c-0-iso10646-1" Then, switch the keyboard to Greek Polytonic: άὰἁἀᾷᾶὰἇῢ I cannot figure out why some characters are excluded and other are not. This issue is not directly related to the upstream bug report in GTK+. -- xkb greek polytonic: cannot write psili and dasia after upgrade to breezy https://launchpad.net/bugs/21637 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
