ISO/IEC 8859-3:1999, Information technology — 8-bit single-byte coded graphic character sets — Part 3: Latin alphabet No.
3,[2] is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1988.
The encoding was popular for users of Esperanto, but fell out of use as application support for Unicode became more common.
ISO-8859-3 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429.
IBM has assigned code page 913 (CCSID 913) to ISO 8859-3.
