ISO/IEC 8859-12 would have been part 12 of the ISO/IEC 8859 character encoding standard series.
ISO 8859-12 was originally proposed to support the Celtic languages.[1][2] ISO 8859-12 was later slated for Latin/Devanagari,[3] but this was abandoned in 1997, during the 12th meeting of ISO/IEC JTC 1/SC 2/WG 3 in Iraklion-Crete, Greece, 4 to 7 July 1997.[4] The Celtic proposal was changed to ISO 8859-14, with part 12 possibly being reserved for ISCII Indian.[5]
WG 3 resolves to suspend any activities on this subject until general agreement on combining characters is obtained and until the further contributions are received.
