I would like a modal text editor (like Vim) with support for proportional fonts.
As a stop-gap measure, I would at least like an editor that lets the em-dash character ("—") consume multiple columns. (In Neovim and Vim, it only consumes one column, and therefore is barely wider than "-".)
Does such an editor exist? I've heard that Emacs supports proportional fonts, but I was unable to install EViL (Vim emulation), presumably because I just don't understand Emacs and its plugin system at all.
