In most contexts, like Firefox of MS Office, if I have text that says, "It’s my birthday" (where the apostrophe has Unicode decimal code 8217) and I search for "It's my birthday" (with a simple apostrophe, decimal code 39) the search matches despite the fact that the two apostrophes are different Unicode characters. However, in Emacs text-mode, the two don't match. Is there a way I can get Emacs's search to consider the two apostrophes the same?
GNU Emacs 24.3.1 (x86_64-apple-darwin, NS apple-appkit-1038.36) of 2013-03-13 on bob.porkrind.org on OS X Yosemite 10.10.5. I'm using a graphic display.
