I'm noticing that there is an inconsistency in the output of one of the compose-key combos.

When I type ( [Compose] . . ) under Chrome, gedit, gnome-terminal, or roxterm I get the character '?'. This is a small raised dot:

$ echo -n '?' | xxd
0000000: cb99                                     ..

When I type the same combo under konsole, yakuake, or kate, I get the character '…'. This is an ellipsis:

$ echo -n '…' | xxd
0000000: e280 a6                                  ...

This is not a font issue: if I copy-paste the characters from an app using one toolkit to an app using the other, its appearance is maintained.

I use a few other combos pretty regularly and they seem to work consistently across toolkits.

I think this is a pretty recent phenomenon. I upgraded from Ubuntu 8.10 to 9.10 fairly recently so this might be related.

I'm not sure if this will reoccur if I restart X, and I'd rather not find out.

Can someone explain how this is possible, and what I can do to resolve it? I'd like to have the ellipsis appear in all apps when that combo is entered.
