Data for mapping between Unicode 1.1, Unicode 2.0 and other hangul encodings has been supplied by the Unicode Consortium. This data is archived as historic, but contains errors; an errata document is also supplied which corrects the mappings with reference to decompositions from the Unicode Character Database for Unicode 1.1.5, which is itself also available. However, the Unicode 1.1.5 data itself contains some errors; corrected data with reference to the ISO/IEC 10646-1:1993 code charts and the source standards is documented in the Unicode Technical Committee document UTC L2/17-080.
