There is some other character between "?" and "✠" on that line.

BTW, instead of including the character literally, you could use a
representation that doesn't rely the file encoding (and leave the literal
character in a comment):

(global-set-key "\C-cM" (lambda () (interactive)  (insert ?\x2720))) ; U+2720 = ✠

or put the literal character in a doc string that you can access with
`C-h k' (M-x describe-key) or `C-h d' (M-x apropos-documentation):

(global-set-key "\C-cM" (lambda ()
			  "Insert U+2720 = \"✠\"."
			  (interactive)
			  (insert ?\x2720)))
