Hi Carsten,
This appears to be an issue in the HEAD (as of two weeks ago) of the
Emacs git repository. I was able to get around this issue (and a
couple
of other font-lock related issues) by stepping back to an older
version
of Emacs (tag EMACS_23_2 in the git repository).
I haven't tried to go back to the Emacs development HEAD, but I assume
that they'll take care of this issue sooner or later, either way it's
not a problem with any of the code in Org-mode.
You may or may not have noticed that there is now also support for
subscripts and superscripts being displayed pretty. This is now realy
how I wanted scientific note taking to work. Need to make a
screencast to show how awesomely this does work.
The only thing missing is a little sketch tool in Emacs, fast enough
to be used while taking notes... :-)
Thanks a lot for you initial implementation of pretty entities - this
has been a breakthrough here.
Where do we stand with integrating org-babel? If you ask me, it is
time to do that.

So looking into this slightly deeper,
I do have org-pretty-entities set to t in my config.
Toggling entities display with C-c C-x \ has no effect.
The value of org-highlight-latex-fragments-and-specials is nil.
Entities are only displayed when I search for the "\\" character, no
other searches result in displayed entities.
Interestingly, when starting with a fresh "emacs -Q" and only
loading
--8<---------------cut here---------------start------------->8---
(load-file "~/src/org/lisp/org-install.el")
(setq org-pretty-entities t)
--8<---------------cut here---------------end--------------->8---
I have the same problem, so maybe my version of Emacs is to blame,
I'm
using the latest from the emacs git/bzr repo

When I get some more time, I'll look into this further.

Hi Carsten,
Thanks for folding in this feature.
I'm having some weird issues using the new entities display. The
entities are not fontified in my org-mode buffers despite having
set
the
org-pretty-entities variable to t. However if I search
`isearch-forward-regexp' for the "\\" character in the buffer then
all
of the entities are displayed (e.g. \sum is replaced with ∑).
Any idea why the entity display is only working during a search?
One idea: Do you have turned on org-highlight-latex-fragments-and-
specials?

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.
