== FIELD DEFINITION AND SCOPE ==


:Used in records encoded with characters from sets other than ISO 10646 (or [http://www.unicode.org/ Unicode]) to specify the character sets for data content that are present in the record. The field alerts users that special processing may be required. A detailed description of the standard escape sequences used in MARC records is provided in [http://www.loc.gov/marc/specifications/ MARC 21 Specifications for Record Structure, Character Sets and Exchange Media].

:Codes for identifying character sets are all but the first character of the escape sequences that designate the sets (the first character is the ''escape character'', hex 1B).
