发布日期: 2020-12-21
这份文件 ? 指定UCS的体系结构; ? 定义用于UCS的术语; ? 描述UCS代码空间的一般结构; ? 指定UCS的指定平面: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)和补充专用平面(SSP); ? 定义一组用于脚本的图形字符,以及全球范围内语言的书面形式; ? 指定BMP、SMP、SIP、TIP、SSP的图形字符和格式字符及其在UCS代码空间中的编码表示形式的名称; ? 指定控制字符和专用字符的编码表示形式; ? 指定UCS的三种编码形式:UTF-8、UTF-16和UTF-32; ? 指定UCS的七种编码方案:UTF-8、UTF-16、UTF-16BE、UTF-16LE、UTF-32、UTF-32BE和UTF-32LE; ? 指定将来添加到此编码字符集的管理。 注:本文件未规定这些字符作为编程语言标识符的适用性,但可在外部参考中找到。见附件U。
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.
