Unicode character entry

[Joe Smith <jes martnet com>]

For the past few years using Gnome on Fedora, I have been able to enter 
arbitrary Unicode characters in any Gnome/Gtk application using 
Ctrl+Shift+U followed by the character's code point as hex digits.

I just upgraded to Fedora 13 which includes Gnome 2.30, and this handy 
feature seems to have disappeared!

I found some advice to use ibus instead, but so far I've not been able 
to get ibus to do what I need without having it interfere with my normal 
typing. I just need a quick way to type common symbols found in English 
text (e.g. an em-dash).

Is this an official Gnome policy, that ibus will be the only way to 
handle input by code point? Or is it a Fedora issue?

Is there any way to get the old behavior?

Thanks for any suggestions or information.
