ANSEL

ANSEL, the American National Standard for Extended Latin Alphabet Coded Character Set for Bibliographic Use, was a character set used in text encoding. It provided a table of coded values for the representation of characters of the extended Latin alphabet in machine-readable form for thirty-five languages written in the Latin alphabet and for fifty-one romanized languages. The standard was reaffirmed in 2003 although it has been administratively withdrawn by ANSI effective 14 February 2013.[1] It is registered as Registration # 231 in the ISO International Register of Coded Character Sets to be Used with Escape Sequences.[2][3]

ANSEL is composed of a set of 63 graphic characters intended for use with ASCII, the American National Standard Code for Information Interchange, ANSI X3.4-1986,[3] including 29 combining diacritic characters. A combining diacritic character precedes the spacing character on which it should be superimposed.[1] The initial revision of ANSEL was released in 1985.

GEDCOM

The GEDCOM specification for exchanging genealogical data refers to ANSEL (ANSI/NISO Z39.47-1985) as a valid text encoding for GEDCOM files and extends it with additional characters which are shown in the following table.[4][5]

MARC21

The Extended Latin character set from MARC 21 is synchronized with ANSEL[3] but additionally supports the eszett (ß) character at C7 and the euro sign (€) at C8.[6]
