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Sets to be Used with Escape Sequences.[2] The standard was reaffirmed in 2003 although it has been administratively withdrawn by ANSI effective 14 February 2013.[3]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]
