ANSEL
ANSEL, American National Standard for Extended Latin Alphabet Coded Character Set for Bibliographic Use, is a character set used in text encoding, and may also be known as
ANSI Z39.47-1985 or
American Library Association character set (as used in library systems including the MARC format).
Rather than having precomposed characters like ISO-8859-1 it codes basic characters and a large number of combining diacritic marks, making it capable of expressing a large range of characters.
