How to disable Ctrl+Shift+U? #

Problem

The problem is that with the “Ibus” input method, Ctrl-shift-u is by default configured to the “Unicode Code Point” shortcut. You can try this: Type ctrl-shift-u, then an (underlined) u appears. If you then type a unicode code point number in hex (e.g. 21, the ASCII/unicode CP for !) and press enter, it is replaced with the corresponding character.

Solution

This shortcut can be changed or disabled using the ibus-setup utility:

• Run ibus-setup from the terminal (or open IBus Preferences).

ibus-setup

• Go to Emoji.
• Next to Unicode code point:, click on the three dots (i.e. …).
• In the dialog, click Delete, then OK.
• Close the IBus Preferences window.
