ELisp section "String and Character Basics": A character is a Lisp object which represents a single character of text. In Emacs Lisp, characters are simply integers; whether an integer is a character or not is determined only by how it is used. *Note Character Codes::, for details about character representation in Emacs. And the cross-reference leads you to a much more detailed description of these issues.
