No, not true. I have always been able to do that with Ubuntu, from
7.04 until my current version, 10.10. I have 11.10 installed on
another machine, and I didn't test it there, so maybe you are right
with that version.
Here are some composed things: © ǒ …– —
And here are some Unicode things: └∆ℌ (I did the first two in gedit,
since Ctrl+Shift+u doesn't work with my web browser Opera, but I did
the last one in Opera, but using Opera's method:
Unicode-hexadecimal-number Ctrl+Shift+x – done).

I didn't do any of this, still I have the Unicode thing AND the Compose thing.

I think I just did. Or maybe I'm just wrong… Well, I have the Compose
and Unicode stuff, but maybe that has something to do with that I
installed Ubuntu in Swedish? But I don't really think so.
