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 The standard was reaffirmed in 2003 although it has been administratively withdrawn by ANSI effective 14 February 2013.^[1] It is registered as Registration # 231 in the ISO International Register of Coded Character Sets to be Used with Escape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]

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]

Hex	Unicode	Glyph	Description
0xBE	25A1	□	empty box
0xBF	25A0	■	black box
0xCD	0065	e	midline e

0xCF	00DF	ß	es zet
0xFC	0338	̸	diacritic slash through char

MARC21

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