ISO/IEC 8859-14
8-bit character set

ISO/IEC 8859-14:1998, part of the ISO/IEC 8859 series of ASCII-based character encodings, is commonly known as Latin-8 or Celtic. Published in 1998, it was designed to support Celtic languages including Irish, Manx, Scottish Gaelic, Welsh, Cornish, and Breton. The IANA prefers this charset name when combined with the C0 and C1 control codes from ISO/IEC 6429. Extensions include CeltScript’s Extended Latin-8, while Microsoft and FreeDOS have assigned code pages Windows-28604 and 58163 respectively to ISO-8859-14.

History

ISO-8859-14 was originally proposed for the Sami languages.3 ISO 8859-12 was proposed for Celtic.4 Later, ISO 8859-12 was proposed for Devanagari, so the Celtic proposal was changed to ISO 8859-14. The Sami proposal was changed to ISO 8859-15,5 but it got rejected as an ISO/IEC 8859 part, although it was registered as ISO-IR-197.6

The original proposal used a different arrangement of points 0xA1–BF.7 At the committee draft stage of the specification, a dotless i was included at 0xAE,8 which was changed to a registered trademark sign (matching ISO-8859-1) in the final publication.

ISO-IR-182, an earlier (registered in 1994) modification of ISO-8859-1, had added the letters Ẁ, Ẃ, Ẅ, Ỳ, Ÿ, Ŵ, Ŷ and their lowercase forms (except for ÿ, which was already included) for Welsh language use.9 The final published version of ISO-8859-14 includes these letters in the same positions which they appear at in ISO-IR-182.

Draft layout

The first draft had positions A0-BF different. It did not include the pilcrow sign, but included the cent sign instead at its Latin-1 position. Later, it was ruled that the pilcrow sign was more common, so the pilcrow sign remains at its Latin-1 position, and the cent sign was removed instead.

Differences from ISO-8859-14 have the Unicode code point below them.
