西夏文
From the earliest days of Unicode, has both influenced and been influenced by the standard—its glyphs first appear in a proposal to the Ideographic Rapporteur Group (IRG), which is responsible for all CJK blocks in Unicode, on 18 April 2002. In May 2007, played a minor role in an eventually successful series of proposals to encode the Tangut script in Unicode; already had within its encoding 6,000 Tangut characters by October 2002.
