Displaying terms as single character unicode symbols in VIM?

Question

Does VIM have a way to show symbols as characters?

So lambda can be displayed as λ (yet keep its underlying ascii text) for example.

Something like emacs pretty-symbols

Answer 1

You can do this with Vim syntax's conceal feature, which allows you to hide matched text or replace it with a single character:

:syntax match keyword "\<lambda\>" conceal cchar=λ
:set conceallevel=1
