Unicode Consortium
The Unicode Consortium cooperates with many standards development organizations, including ISO/IEC JTC 1/SC 2 and W3C. While Unicode is often considered equivalent to ISO 10646, and the character sets are essentially identical, the Unicode standard imposes additional restrictions on implementations that ISO 10646 does not. Apart from "The Unicode Standard" (TUS) and its annexes (UAX), the Unicode Consortium also maintains the CLDR, collaborated with the IETF on IDNA, and publishes related standards (UTS), reports (UTR), and utilities.
