ISO/IEC 8859-15

ISO/IEC 8859-15:1999, Information technology — 8-bit single-byte coded graphic character sets — Part 15: Latin alphabet No. 9, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1999. It is informally referred to as Latin-9 (and for a while Latin-0). It is similar to ISO 8859-1, and thus also intended for “Western European” languages, but replaces some less common symbols with the euro sign and some letters that were deemed necessary:^[1] This encoding is by far most used, close to half the use, by German, though this is the least used encoding for German.

ISO-8859-15 is the IANA preferred charset name for this standard when supplemented with the C0 and C1 control codes from ISO/IEC 6429.

Microsoft has assigned code page 28605 a.k.a. Windows-28605 to ISO-8859-15. IBM has assigned code page 923 (CCSID 923) to ISO 8859-15.^[2][3]

All the printable characters from both ISO/IEC 8859-1 and ISO/IEC 8859-15 are also found in Windows-1252. Since October 2016, less than 0.1% (actually currently less than 0.02%) of all web sites use ISO-8859-15.^[4][5]
