It is applicable to therepresentation, transmission, interchange, processing, storage, input, and presentation of the written formof the languages of the world as well as of additional symbols.This International Standard?? specifies the architecture of this International Standard,?? defines terms used in this International Standard,?? describes the general structure of the UCS codespace,?? specifies the Basic Multilingual Plane (BMP) of the UCS,?? specifies supplementary planes of the UCS: the Supplementary Multilingual Plane (SMP), the SupplementaryIdeographic Plane (SIP), the Tertiary Ideographic Plane (TIP), and the SupplementarySpecial-purpose Plane (SSP),?? defines a set of graphic characters used in scripts and the written form of languages on a world-widescale,?? specifies the names for the graphic characters and format characters of the BMP, SMP, SIP, TIP,SSP and their coded representations within the UCS codespace,?? specifies the coded representations for control characters and private use characters,?? specifies three encoding forms of the UCS: UTF-8, UTF-16, and UTF-32,?? specifies seven encoding schemes of the UCS: UTF-8, UTF-16, UTF-16BE, UTF-16LE, UTF-32, UTF-32BE, and UTF-32LE,?? specifies the management of future additions to this coded character set.The UCS is an encoding system different from that specified in ISO/IEC 2022.
