?A is elisp syntax for the character A. That's different from the string containing
A which is denoted "A". As the docstring for the variable indicates, it expects
a *character* as the car of the pair.

OK - sorry I screwed that up.

Probably the "Emacs Lisp Intro" tutorial which comes with your emacs I believe:
C-h i m Emacs Lisp Intro RET

No wildcards used here - not sure what you mean. If you mean the ? in ?A it's
most definitely *not* a wildcard.

These are obscure (but hallowed by long history) names of the basic operations
in Lisp. Lisp's basic data structure is called a (dotted) pair: cons takes two
things and constructs a dotted pair out of them. car and cdr (the names mean
nothing unless you happen to know the architecture of some ancient IBM computer
where Lisp was first developed) are selectors: car takes a pair and returns
the first part of it, cdr returns the second part.
