There's no reason to learn vi if you know Emacs. If you claim that Emacs isn't installed everywhere, guess what: Neither is vi.

If you want an "installed everywhere" editor, learn ed. If you're willing to take an editor with you (or otherwise make sure a specific editor is everywhere you are), there's no reason it has to be vi.

Do not. Having a non-utf8 locale means you won't be able to handle utf-8 sanely ("that's why it's faster") and it will break at the most inexplicable times. Any non-latin1 character appearing in your prompt or command line with this will mess its spacing up for example. Do not do not do not.

Hell I even check for it in my .zshrc: https://github.com/jleclanche/dotfiles/blob/master/.zshrc#L3...

Good post otherwise.

I have to reiterate this; don't do it -- sort order changes and you'll run into other mysterious issues.

It's not worth the "performance improvement".

vi is a posix requirement, emacs is not. If the system you're working on has ed, it'll have some version of vi or vim as well.
