german umlaut ä is overmapped

seebi commented 10 years ago

using vim-rsi, unfortunately I can not use my ä-key anymore ...

That seems to be caused by <M-d> mapping here.

Here's how I debugged (classic US keyboard btw):

set let g:loaded_rsi=1 in .vimrc
have set macmeta in .vimrc
open macvim. Typing alt-d produces ä character in insert mode
next, execute this: noremap! <M-d> <C-O>dw and alt-d does not produce ä in insert mode anymore

Theory why this happens (I'm not 100% sure on this):

character d is represented with ascii 01100100 (that's 100 in decimal)
character meta-d is the same as d but with highest binary bit set to 1 - 11100100 (that's 228 decimal)
search for 11100100 on the extended ascii page and you see it's umlaut-a character ä
to simplify <M-d> is ä (and vice versa I suppose). When M-d is remapped, ä is changed as well

I hope this helps. I don't know the solution.

I'm afraid the only solution will be an option to turn off the meta maps.

Another option is to revert the <M-d> mapping in ~/.vim/after/plugin/rsi.vim:

iunmap <M-d>
cunmap <M-d>

if !has("gui_running")
  set <F31>=
  unmap! <F31>
  unmap <F31>
endif

edit: Just realized with Neovim this isn't necessary anymore.

This is also the case when using the danish keyboard layout, where vim-rsi breaks the "æ" key.
