Unicode and ISO 10646
Q: What is the relation between ISO/IEC 10646
and Unicode?
A: 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. [EH]
Q: So are they the same thing?
A: No. Although the character codes and encoding forms are synchronized
between Unicode and ISO/IEC 10646, the Unicode Standard imposes
additional constraints on implementations to ensure that they treat
characters uniformly across platforms and applications. To this end, it
supplies an extensive set of functional character specifications,
character data, algorithms and substantial background material that is
not in ISO/IEC 10646.
Q: Where do I find out which version of ISO/IEC 10646 is
equivalent to a given version of the Unicode Standard?
A: Each version of the Unicode Standard identifies the corresponding version of ISO/IEC 10646. Start with http://www.unicode.org/versions/ and, in the navigation bar on the left, follow the link for the version you are interested in. The overview page for each version provides information about the relation to ISO/IEC 10646 versions in the summary or overview part near the top. Some versions of the Unicode standard are synchronized to a combination of ISO/IEC 10646 and one or more amendments. [AF]
Q: How do I get a copy of ISO/IEC 10646 ?
A: You can order copies of ISO/IEC 10646 and its amendments
directly from the
ISO Store or from the ANSI
e-Standards Store.
Q: Is ISO/IEC 10646 also available for free download?
A: Yes. ISO/IEC 10646:2014 is available for free download from: http://standards.iso.org/ittf/PubliclyAvailableStandards/index.html.
