SUMMARY Can only enter unicode with ctrl+shift+u when Virtual Keyboard is enabled and set to Ibus Wayland STEPS TO REPRODUCE 1. Have the default virtual keyboard setting, Maliit. 2. Open a non-GTK app with text entry, like kwrite or zed editor. 3. Press ctrl+shift+u 4. Change vitual keyboard to "Ibus Wayland" and click the widget to enable the virtual keyboard 5. Press ctrl+shift+u in the non-GTK text field again. OBSERVED RESULT Nothing happens at step 3. At step 5, Underlined "u" appears in text entry field, ready for direct unicode codepoint entry. For example, ctrl+shift+u 394 -> Δ, b0 -> °, etc. EXPECTED RESULT Default configuration behaves as in step 5.

That makes sense since this is an IBus-specific feature. :) Unfortunately right now input methods are mutually exclusive. You can use IBus or Maliit, but not both at the same time. Ideally this would change in the future, but it's a multi-year project due to the technical complexities involved.
