标准摘要
[中文适用范围]： 本文件规定了UCS的架构；定义了UCS使用的术语；描述了UCS编码空间的通用结构；指定了UCS的分配平面：UCS的基本多语言平面（BMP）、补充多语言平面（SMP）、补充表意平面（SIP）、第三表意平面（TIP）和补充特殊用途平面（SSP）；定义了一套在全球范围内用于脚本和语言书面形式的图形字符；指定了BMP、SMP、SIP、TIP、SSP的图形字符和格式字符的名称及其在UCS编码空间中的编码表示；指定了控制字符和私有使用字符的编码表示；指定了UCS的三种编码形式：UTF-8、UTF-16和UTF-32；指定了UCS的七种编码方案：UTF-8、UTF-16、UTF-16BE、UTF-16LE、UTF-32、UTF-32BE和UTF-32LE；指定了未来添加到此编码字符集的管理。 [外文原描述]： This document specifies the architecture of the UCS; defines terms used for the UCS; describes the general structure of the UCS codespace; specifies the assigned planes of the UCS: the Basic Multilingual Plane (BMP) of the UCS, the Supplementary Multilingual Plane (SMP), the Supplementary Ideographic Plane (SIP), the Tertiary Ideographic Plane (TIP), and the Supplementary Special-purpose Plane (SSP); defines a set of graphic characters used in scripts and the written form of languages on a world-wide scale; 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. NOTE The determination of suitability of these characters for use as identifiers in programming languages is not specified by this document but can be found in an external reference. See Annex U.
