elisp: Strings and Characters

 
 4 Strings and Characters
 ************************
 
 A string in Emacs Lisp is an array that contains an ordered sequence of
 characters.  Strings are used as names of symbols, buffers, and files;
 to send messages to users; to hold text being copied between buffers;
 and for many other purposes.  Because strings are so important, Emacs
 Lisp has many functions expressly for manipulating them.  Emacs Lisp
 programs use strings more often than individual characters.
 
    Strings of Events, for special considerations for strings of
 keyboard character events.
