Section: 4.2.1 Introduction to character strings

Begin quoting
A character string is a sequence of characters. All the characters in a
character string are taken from a single
character set. A character string has a length, which is the number of
characters in the sequence. The length is
0 (zero) or a positive integer.
End quoting
