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 The standard was reaffirmed in 2003 although it has been administratively withdrawn by ANSI effective 14 February 2013.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

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, including 29 combining diacritic characters. A combining diacritic character precedes the spacing character on which it should be superimposed.

The following table shows ANSI/NISO Z39.47-1993 (R2003). Each character is shown with its Unicode equivalent.

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.

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