I thought, I would mention digraphs, because they could be useful here.
That means typing <Ctrl-K> '=' '>' should give you the same character. (I
don't see it here, as my font, does not seem to provide a glyph here).
It is also worth at least considering to set the 'digraph' option. If it
is set, you type the first key, backspace and the second key and it will
result in your digraph. (e.g. pressing 'a', <BS>, ':' results in ä)

I never got around to use the compose key much, because I never found a
good overview, which mappings result in which glyphs. But then, I only
need those multibyte chars very seldom (except for äöüß, which are on my
keyboard anyway).

The f and t commands work when using digraphs. I.e. if you want to
jump to the ä, you press f <Ctrl-K> a : and f jumps to the ä
(but don't work when 'digraph' is set and you want to enter them using
the backspace key).
Oh, and then there is this plugin, I wrote long ago. It provides digraph
and Unicode completion. http://www.vim.org/scripts/script.php?script_id=2822
(don't know if it useful, but I thought, I'd mention it anyway).

I still feel that way. I never found it of any personal use for me. I
even mapped it away.
