What is the relation between ISO-10646 and Unicode?
In 1991, the ISO Working Group responsible for ISO/IEC 10646 (JTC 1/SC 2/WG 2) and the Unicode Consortium decided to create one universal standard for coding multilingual text. Since then, the ISO 10646 Working Group (SC 2/WG 2) and the Unicode Consortium have worked together very closely to extend the standard and to keep their respective versions synchronized.
