ISO/IEC 8859-2:1999, Information technology — 8-bit single-byte coded graphic character sets — Part 2: Latin alphabet No. 2, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as "Latin-2". It is generally intended for Central[1] or "Eastern European" languages that are written in the Latin script. Note that ISO/IEC 8859-2 is very different from code page 852 (MS-DOS Latin 2, PC Latin 2) which is also referred to as "Latin-2" in Czech and Slovak regions.[2] Almost half the use of the encoding is for Polish, and it's the main legacy encoding for Polish, while virtually all use of it has been replaced by UTF-8 (on the web).

ISO-8859-2 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429. Less than 0.04% of all web pages use ISO-8859-2 as of October 2022.[3][4] Microsoft has assigned code page 28592 a.k.a. Windows-28592 to ISO-8859-2 in Windows. IBM assigned code page 912 to ISO 8859-2,[5] until that code page was extended in 1999.[6] Code page 1111 is similar, but replaces byte B0 ° (degree sign) with U+02DA ˚ (ring above).

Windows-1250 is similar to ISO-8859-2 and has all the printable characters it has and more. However a few of them are rearranged (unlike Windows-1252, which keeps all printable characters from ISO-8859-1 in the same place).

Language coverage

[edit]

These code values can be used for the following languages:

  1. ^ The missing letter Å is officially a part of the Finnish alphabet, however it has no native use and its usage is limited to foreign names only.
  2. ^ In 2017, the Council for German Orthography officially added a capital , but is not actually required as SS can be used instead.
  3. ^ This character set unifies Ș and Ț (S,T with commas below) with Ş and Ţ (S, T with cedillas), as did virtually all other character sets including Microsoft's Windows-1250 and the first version of Unicode. Unicode subsequently disunified them however, this complicated processing of Romanian data; pre-existing data and input methods would still contain the older cedilla codepoints, complicating text searching.[citation needed]
