Description of problem:
For years I've been able to type <ctrl><shift>u to enter unicode input mode and type the hex value of a unicode character. Now it does nothing.

How reproducible:
While in an application that lets you enter text press <ctrl><shift>u226c followed by a space

Actual results:
Nothing

Expected results:
Output of two notes

Additional info:
Please don't say use <ctrl><shift>e for the emoji chooser. It can not substitute for the missing behavior. It's a chooser not an inline input method.

For some reason the emoji chooser HAS unicode but it's horrible! It's also weird. Why is unicode in an emoji chooser? Who would want to use that? It takes you off to a different window which disappears randomly behind the input screen while you're trying to use it. Whoever created it seems to have no experience with usability. I'm a software engineer with decades of experience and we had to take classes in usability in college. Don't they teach that anymore? 

I have to select unicode from a list and then search for the unicode character I already know the code point for. It's pretty ghastly. Then when I find it and select it the creepy window doesn't even go away!!! Whoever created it seems really proud of it and just wants it to stay around.
