Hi everyone,
a modified version of Eric's code is now included into Org, I just
pushed it
to the git repo.
You can use the command `C-c C-x \' to toggle this feature.
The variable `org-pretty-entities' determines if this mode is on by
default.
Finally, you can use
#+STARTUP: entitiespretty
#+STARTUP: entitiesplain
to change things on a per-file base.
Thanks to Eric for this great idea.

Hi,
Recently I've been making use of org-entites for exporting my greek/
math
heavy class notes to HTML. I'm really loving the results.
This morning I've started playing around with the below function
`org-pretty-entities', which is adapted from Phil Hagelberg's
`pretty-lambdas'[1]. Calling this function in an org-mode buffer will
have the effect of fontifying all org-entities text strings as the
character which they represent, so \Delta is replaced with Δ, \lambda
with λ, \in with ∈, and so forth.
I've just started playing with this, and I make no guarantees as to
it's
safety or utility, but I was very pleasantly surprised by the
simplicity
of the function, and how nice it's been to see my special characters
appear in org-mode buffers as I type.
#+begin_src emacs-lisp :results silent
(defun org-pretty-entities ()
(interactive)
(font-lock-add-keywords
nil (mapcar
(lambda (el)
(list
(concat "(?\\(" (regexp-quote "\\") (nth 0 el) "[\s]" "\
\)")
`(0 (progn (compose-region (match-beginning 1) (- (match-
end 1) 1)
,(nth 6 el)) nil))))
org-entities)))
(org-pretty-entities)
#+end_src
To try this out, just evaluate the above code block inside of an
org-mode buffer, then starting typing out org-entities.
Hope others find this useful.
Best -- Eric
