Only problem with those imaps is that now you can't type ì, ë, ê, or è. Vim is pretty dumb about utf-8.

I'd also suggest using <C-o> instead of the <Esc>...i dance.

I think I solved that problem quite elegantly :) However I still have a small TODO regarding printing from cygwin:

    set encoding=utf-8
    " TODO check if printing of utf-8 chars works with 'set fileencoding=utf-8'
    set fileencoding=utf-8


    " {{{ Diacritic characters: <Leader>char (keyboard switching doesn't work in cygwin)
    " Use the same keys as on a keyboard
    inoremap <Leader>; ö
    inoremap <Leader>: ö
    inoremap <Leader>' ä
    inoremap <Leader>" Ä
    inoremap <Leader>[ ü
    inoremap <Leader>{ Ü
    inoremap <Leader>- ß

    " Comment/Uncoment following as you need:

"Vim is pretty dumb about utf-8."

It might not work the way you prefer using your favorite input method, but vim allows you to enter any utf-8 character, and even has mnemonic digraphs for many you are most likely to want. To get è, for example, in input mode just type <ctl>-k`e.

[graywh]

Using the digraph will get around the insert-mode alt-key maps.

or `, delete, e if digraphs are activated (IIRC)

[saraid216]

I code on a Macbook, and I actually use say... Option+i, e in order to get ê. That works inside Vim, too, I just found out.

Obviously not very helpful to people not on a Mac, but I don't have to go through Alt mappings at all.

[graywh]

The point of my comment is that with an imap on <a-j>, you can't input the character ê because it will trigger the mapping. This includes option+i, e on OS X.
