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. ANSEL adds 63 graphic characters to ASCII,[1] including 29 combining diacritic characters.

The initial revision of ANSEL was released in 1985, and before 1993 it was registered as Registration #231 in the ISO International Register of Coded Character Sets to be Used with Escape Sequences.[2] The standard was reaffirmed in 2003 although it has been administratively withdrawn by ANSI effective 14 February 2013.[3]

The requirement of hardware capable of overprinting accents doomed this from ever becoming a popular extended ASCII.[citation needed]

Code page layout

The following table shows ANSI/NISO Z39.47-1993 (R2003).[3] Non-ASCII characters are shown with their Unicode code point. A combining diacritic precedes the spacing character on which it should be superimposed[1] (in Unicode the combining diacritic is after the base character).

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
0xCE 006F o midline o
0xCF 00DF ß es zet
0xFC 0338  ̸  diacritic slash through char

MARC21

The Extended Latin character set from MARC 21 is synchronized with ANSEL[2] but additionally supports the eszett (ß) character at C7 and the euro sign (€) at C8.[6]
