imap and the r operation

Question

I write in English and Swedish in vim and have the lines below in my .vimrc to switch to and from a pseudo-Swedish keyboard layout. Basically some keys are remapped with inoremmap when doing <Leader>s to output Swedish characters, and characters that are masked by this are reached by hitting the key twice. <Leader>e undoes these mappings to return to English typing. This all works fine except for with the r operation. For example, when the Swedish mappings are in effect, r[ does not change the letter to å, but to [. How can I make these mappings also affect the r operation?

Note that I do not want to use the OS's keyboard switch since this would effect operations in normal mode.

" Switch to Swedish
function! SweType()
  set spelllang=sv
  inoremap ; ö
  inoremap ;; ;
  inoremap : Ö
  inoremap :: :
  inoremap [ å
  inoremap { Å
  inoremap ' ä
  inoremap '' '
  inoremap " Ä
  inoremap "" "
  inoremap [[ [
  inoremap {{ {
endfunction
nmap <Leader>s :<C-U>call SweType()<CR>


" Switch to English
function! EngType()
  set spelllang=en_us
  inoremap ; ;
  iunmap ;;
  inoremap : :
  iunmap ::
  inoremap [ [
  iunmap [[
  inoremap { {
  iunmap {{
  inoremap ' '
  iunmap ''
  inoremap " "
  iunmap ""
endfunction
nmap <Leader>e :<C-U>call EngType()<CR>

Answer 1

You should be able to remap the whole sequence of keys in normal mode :

nnoremap r[ rå

Edited the answer, as I'm not sure in which mode we are when we hit r. Maybe a sub mode of insert mode that is left as soon as another key is pressed.
