~/.vimrc: Fix some encoding problems

I _think_ this was for when editing weird files, but I don't really
know.

.vimrc

" Don't let me further than 1 line towards the end or the beginning.
set scrolloff=1
set fileencodings=utf-8
set encoding=utf-8
" Show whitespace
set list
set listchars=tab:→\ ,trail:·,eol:¬
"highlight SpecialKey ctermfg=10 ctermbg=8
"highlight NonText ctermfg=10 ctermbg=8
set fileencodings=utf-8
" Automatically reread the file if it has been changed from the outside
set autoread
