What is wide character string?

A wide character-string value is a sequence of double-byte characters or byte-pairs. The number of byte-pairs in a wide character string or sequence is called the length of the string or sequence. In Open PL/I, the maximum length of a wide string value is 16383 byte-pairs or double-byte characters.
