By reading the documentation, of course.

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.
