What attribute goes to play when Ctrl+Shift+Alt+U, E "types" an unprintable hex 000E?

I often tend to make use of Ctrl+Shift+Alt for my tailored system - vast keybindings.

When I attempted Ctrl+Shift+Alt+U it published an emphasized u and also awaited even more key-board input! ...
Some keys were approved and also some were not ...
eg. Numbers were approved and also they also were underscored, yet just a couple of keys permitted me to burst out.

I after that attempted Ctrl+Shift+Alt+U quickly adhered to by Ctrl+Shift+Alt+E.
This generated an unprintable hex 000E (?) and also burst out of the loop ...

The unprintable personality obtained me assuming that this might be Unicode relevant.

If so, just how so? What is taking place below?
Is this emphasized u a trigger for an Input Method Editor?

This practices takes place : Here (as I type), "gedit", message - edit areas ... (yet not in the Terminal) ... and also "gvim" reported "pattern not found" ...

Ctrl - Shift - U is the brief - cut to start getting in a complete unicode personality by hand. As an example, below I've keyed in : Ctrl - Shift - U 0 0 b 0 enter to get the level icon : ° which is unicode 00b0. Below is 2665, the heart : ♥
