Cool, I've been bugged for too long by the time it takes to insert a
named Unicode character.

What I've really been missing though is some "ido-like" equivalent of
ucs-insert, since I often don't know what the Unicode name for the
character is. As an example, if I want to insert λ, which is "GREEK
SMALL LETTER LAMBDA", it's not easy to know what the name is
beforehand.
