Yea, I have the following org-entites customization in my setup which
covers some of the symbol names I commonly expect. It's been growing
the more I use org-entities.
--8<---------------cut here---------------start------------->8---
(add-to-list 'org-entities
'("supseteq" "\\supseteq" t "⊇" "[superset of or equal to]"
"[superset of or equal to]" "⊇"))
(add-to-list 'org-entities
'("subseteq" "\\subseteq" t "⊆" "[subset of or equal to]"
"[subset of or equal to]" "⊆"))
(add-to-list 'org-entities
'("subseteq" "\\subseteq" t "⊆" "[subset of or equal to]"
"[subset of or equal to]" "⊆"))
(add-to-list 'org-entities
'("leq" "\\leq" t "≤" "<=" "<=" "≤"))
(add-to-list 'org-entities
'("geq" "\\geq" t "≥" ">=" ">=" "≥"))

agreed, maybe this would be better (using [:alnum:])? The only reason
for the restriction is to keep symbols from appearing mid way through
typing out some other symbol or word.
--8<---------------cut here---------------start------------->8---
(defun org-pretty-entities ()
(font-lock-add-keywords
nil (mapcar
(lambda (el)
(list
(concat "(?\\(" (regexp-quote "\\") (nth 0 el) "[^[:alnum:]]" "\\)")
`(0 (progn (compose-region (match-beginning 1) (- (match-end 1) 1)
,(nth 6 el)) nil))))
org-entities)))

Those both sound great. It would take a little bit of effort to look
into how to remove font-lock keywords. If you have the time and
inclination please go ahead with this, otherwise I should be able to
take a shot at it myself in the next week or two -- I'm in the middle of
my final exams right now.
