Control Shift C - copy or unicode entry?

[Nigel Tao]

Found out by accident that Control-Shift-E6 (that's the "E" key followed
by the "6" key followed by releasing Ctrl and Shift) actually gives me
unicode E6, or æ.  Neat feature.

Unfortunately, my application (Eclipse) is expecting Control-Shift-E
(and Control-Shift-F) to accelerate a menu option, and is not receiving
it.  Is there anyway to disable the Control-Shift-starts-unicode-entry
feature, since I do not use it?  Or somehow make the app over-ride?

I noticed that gnome-terminal sometimes lets Control-Shift-C start a
unicode entry, but captures Control-Shift-C for copy when something is
selected by mouse (although it's hard to tell exactly what is going on,
since the very act of selecting the text by mouse performs a copy).
