Конфигурация

Конфигурация vim хранится в файлах: ~/.vimrc и ~/.gvimrc
Узнать какой именно файл используется можно прямо в vim командами:

:echo $VIM
:echo $MYVIMRC

У каждого свой конфиг Vim. У меня достаточно простой:

Для переключения Vim в en_US.UTF-8 внутри Windows можно добавить:

set enc=utf-8
set fileencoding=utf-8
set langmenu=en_US.UTF-8
let $LANG='en_US.UTF-8'
language messages en

и запускать gvim с помощью ключа:

gvim --cmd "lang English_United States"
