标准范围

ISO/IEC 10646:2017规定了通用编码字符集（UCS）。它适用于世界语言和其他符号的书面形式的表示、传输、交换、处理、存储、输入和表示。-规定了本国际标准的体系结构，-定义了本国际标准中使用的术语，-描述UCS代码空间的一般结构，-指定UCS的基本多语言平面（BMP），-指定UCS的补充平面: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），-定义了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。UCS是一种不同于ISO/IEC 2022中规定的编码系统。ISO/IEC 2022中指定UCS的方法见第12节。2.图形字符将在标准中仅分配一个代码点，位于BMP或一个补充平面中。

ISO/IEC 10646:2017 specifies the Universal Coded Character Set (UCS). It is applicable to the represen-tation, transmission, interchange, processing, storage, input, and presentation of the written form of the lan-guages of the world as well as of additional symbols.- 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 Supplemen-tary 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.The UCS is an encoding system different from that specified in ISO/IEC 2022. The method to designate UCS from ISO/IEC 2022 is specified in 12.2.A graphic character will be assigned only one code point in the standard, located either in the BMP or in one of the supplementary planes.
