how to automatically remove org-emphasis markers, i.e. org-deemphasize?

Question

There is a function org-emphasize, which wraps selected text in org-emphasis markers. (Though I personally use a similar function called wrap-region.)

Is there a function org-deemphasize (or analogously, unwrap-string-at-point) that will remove org-emphasis markers before and after point? (Without my having to manually select the exact region?)

It should refer to org-emphasis-alist For example, my customized org-emphasis alist looks like this:

(("*" bold)
("/" italic)
("_" underline)
("=" org-code verbatim)
("~" flyspell-incorrect)
("+"
(:strike-through t)))
