In my scripts I use this construction -- seems ugly, but works:
function <SID>Process()
let [buf, row, col, off] = getpos(".")
let [whole, before, old, after; rest] =
\ matchlist(getline("."), printf('^\(.\{-}\)\(.\?\)\%%%dc\(.*\)$', col))
" old now contains the char under cursor, in the following code
" we are replacing it with something else
let new = SomethingElse();
let col = col - strlen(old) + strlen(new)
call setline(".", before . new . after)
call setpos(".", [buf, row, col, off])
return ""
endfunction
The regexp seems complex because it should process even the corner
cases, such the cursor after the last character in insert mode.
