There are three general types of GUI applications, 1. Xlib applications, which are GUI programs that use directly low-level X functions to draw windows. Example: 'xterm'. Ctrl+Shift+u+UniValue never worked for these apps. See: https://bugs.freedesktop.org/show_bug.cgi?id=26747 2. gtk+ applications, GUI apps that make use of the gtk+ library, found in GNOME and also in Firefox and OpenOffice.org. Firefox and OpenOffice.org are not full GNOME apps as they do not use the full GNOME stack of libraries. In OpenOffice, for example, there is no right-click/input methods menu due to this. Here Ctrl+Shift+u works as long as GTK_IM_MODULE is not set to 'xim' (which means that gtk+ apps become like type '1' apps in terms of input). 3. QT apps, GUI apps that use the QT library, commonly the KDE applications. Here there have been no Ctrl+Shift+u support. See: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/531208 https://bugs.kde.org/show_bug.cgi?id=103788 >>The "complication" may appear if you enable Chinese, Korean, Japanese >>or similar complex "input method" support.

Here is the source code of the IPA input method; http://git.gnome.org/browse/gtk+/tree/modules/input/imipa.c It does show that it supports combining diacritics with U+0303, so aããẽg̃h̃t̃ỹũĩõk̃l̃m̃ñb̃ṽc̃x̃z̃q̃w̃ẽr̃t̃ỹũĩõp̃l̃k̃m̃ñ and ɹ̃ and ŗ̃ and ɨ. Line 125, GDK_asciitilde, 0, 0, 0, 0, 0x303, /* COMBINING TILDE */ could be replicated in order to support any other combining diacritics. The alternative option for IPA would be to try IBus and locate a suitable layout. The predecessor of IBus is SCIM, and it should be possible to use SCIM layouts in IBus. Google for 'SCIM IPA' or ask the IBus mailing list. > It appears that Fedora 11 is the last version of Fedora I will be able > to use. I would be interested to verify whether 'xterm' (Xlib app) or a QT app is able to support Ctrl+Shift+U. Can you check 'xterm' and tell me which QT app you tried?
