 That's #82260.

 The problem there is - how are you going to feed that character to the 
running application? If you add this feature to khotkeys then after khotkeys 
handles the user input and knows it has to enter <some char> to the running 
app, it needs to tell it. Input action in khotkeys simply sends XKeyEvent to 
the active app, but that one only contains keycode and modifiers state. And 
you cannot enter <some obscure unicode char> this way if you can't find the 
keycode and modifiers state for it (and you generally can't, otherwise you'd 
simply type it in normally). So I think this needs at least some code in the 
applications for it.
