ISO/IEC 8859-1:1998, Information technology — 8-bit single-byte coded graphic character sets — Part 1: Latin alphabet No. 1, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. ISO 8859-1 encodes what it refers to as "Latin alphabet no. 1," consisting of 191 characters from the Latin script. This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa. It is also commonly used in most standard romanizations of East-Asian languages. It is the basis for most popular 8-bit character sets, including Windows-1252 and the first block of characters in Unicode.
As of November 2016[update], 5.7% of all web sites claim to use ISO 8859-1, however this includes an unknown number of pages actually using Windows-1252 and/or UTF-8, both of which are commonly recognized by browsers despite the character set tag.
ISO-8859-1 is the IANA preferred name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429 (see below for HTML5 exception). The following other aliases are registered for ISO-8859-1: iso-ir-100, csISOLatin1, latin1, l1, IBM819, CP819.
The Windows-1252 codepage coincides with ISO-8859-1 for all codes except the range 128 to 159 (hex 80 to 9F), where the little-used C1 controls are replaced with additional characters including all the missing characters provided by ISO-8859-15. Code page 28591 a.k.a. Windows-28591 is the actual ISO-8859-1 codepage.
