Hi
I was wondering if there is a way to fontify expressions like M_x^y
correctly with org-pretty-entities.
M_x^y displays the subscript x correctly but not the superscript y.
M^y_x displays the superscript y correctly but not the subscript x.
Regards,
Laurent

M_x ^y is the only (non fully satisfactory) solution I can think of.

In general org entities work wonders, and I'm a very happy user.
I have a couple of others things that could be made nicer (somehow).
'===>' indicates what would be nicer:
- \frac{x}{y} ===> [(x)/(y)] or something similar. You'd need to be
able to see that it was folded, somehow, e.g. '[' could have
another color, or the background of (x)/(y) could be different.
- \bar{x}, tilde{x}, underline{x}, ... ==> constructed using
combining utf8 characters ¹ (or at least support of it; i couldn't
get it working properly)
- Being able to specify several white spaces (it seems not to work,
e.g. below I would like to replace quad with " ␣ ", but this
doesn't seem to work...).
- perhaps overlay to indicate when something is folded/replaced with
a utf8 character.
Here's my org-entities-user btw:
(setq org-entities-user '(("space" "\\ " " " " " " " " ")
("implies" "\\Rightarrow" t "⇒" "=>" "=>" "⇒")
("iff" "\\iff" t "⇔" "<=>" "<=>" "⇔")
("succcurlyeq" "\\succcurlyeq" t "≽" ">=" ">=" "≽")
("gimel" "\\gimel" t "ℷ" "gimel" "gimel" "ℷ")
("beth" "\\beth" t "ב" "bet" "bet" "ב")
("coloneqq" "\\coloneqq" t "≔" ":=" ":=" "≔")
("eqqcolon" "\\eqqcolon" t "≕" "=:" "=:" "≕")
("cdots" "\\cdots" t "…" "..." "..." "⋯")
("colon" "\\colon" t ":" ":" ":" ":")
("quad" " " nil " " " " " " "␣")
("geq" "\\ge" t "≥" ">=" ">=" "≥")
("suchthat" "\\suchthat" t "|" "|" "|" "|")
("leq" "\\leq" t "≤" "<=" "<=" "≤")))
All but suchthat are normal LaTeX characters.
Perhaps, org entities could use the TeX input method as a souce of
symbols? See:
(describe-input-method "TeX")

We've been at this before, but I believe that introducing utf8
characters into the sources would cut off Emacs 22 compatibility. There
is a known bug when more-than-single-byte characters show up in a
docstring as well.

If the facts have been changing once, I can wait for them to change
again. Or they may not even be facts after all. :-)

Achim.

This opens up my mind a lot, thanks :)

Perhaps that opinion is too dear for some practitioner, as Lord Keynes
was when he allegedly spoke those words. What if the 'facts' only
converge back to your preferred state in the long run, when we are all
dead? :)

The original quote[1] is really a lot better and I have much more trust
in its accuracy than the later quote you gave:
"When my information changes, I alter my conclusions. What do you do, sir?"
I don't know why it was altered to the second, I'll give that it is
punchier at first sight due to that double "change", but it makes a lot
less sense. It may have been saved if it started "When I learn of new
facts,…", but that loses some punch again.
