ISO/IEC 2375:2003规定了准备、维护和发布转义序列及其标识的编码字符集的寄存器应遵循的程序。 ISO/IEC 2375:2003中规定的注册过程不是字符或编码字符集标准化的程序。希望ISO和/或IEC为编码字符集创建国际标准或希望ISO和/或IEC将附加字符编码到ISO/IEC 10646中的组织需要遵循ISO/IEC程序进行此操作。 特别是， 根据ISO/IEC 2375:2003规定的程序注册编码字符集并不意味着ISO和/或IEC承诺采用编码字符集作为ISO/IEC标准。在批准的注册中存在一个字符并不意味着ISO和/或IEC承诺将该字符编码到ISO/IEC 10646中。ISO/IEC 2022描述了ISO/IEC 2375:2003中引用的逃逸序列，但ISO/IEC 2022中保留供私人使用的逃逸序列除外。 根据ISO/IEC 2022，这些转义序列的使用包括代码扩展，即提供附加字符集或附加控制功能。 根据ISO/IEC 2375:2003注册的转义序列用作寄存器中字符、字符集或与其相关联的控制功能的标识。 注册本身不指定使用由转义序列标识的字符或字符集所依据的规则。相反，注册识别指定此类规则的文件（例如标准）。

ISO/IEC 2375:2003 specifies the procedures to be followed for preparing, maintaining, and publishing a register of escape sequences and of the coded character sets they identify. The registration process specified in ISO/IEC 2375:2003 is not a procedure for standardization of characters or coded character sets. Organizations that wish ISO and/or IEC to create an international standard for a coded character set or that wish ISO and/or IEC to code additional characters into ISO/IEC 10646 need to follow the ISO/IEC procedures for doing so. In particular,

• Registration of a coded character set according to the procedures specified by ISO/IEC 2375:2003 implies no commitment by ISO and/or IEC to adopt the coded character set as an ISO/IEC standard.
• The existence of a character in an approved registration does not imply a commitment by ISO and/or IEC to encode that character into ISO/IEC 10646.

ISO/IEC 2022 describes the escape sequences referenced in ISO/IEC 2375:2003, except for escape sequences reserved in ISO/IEC 2022 for private use. The use of these escape sequences includes code extension, that is, the provision of additional sets of characters, or of additional control functions, in accordance with ISO/IEC 2022. An escape sequence registered in accordance with ISO/IEC 2375:2003 serves as an identification of the character, the set of characters, or the control function associated with it in the register. The registration itself does not specify the rules in accordance with which a character or character set identified by an escape sequence is to be used. Rather, the registration identifies the documents (for example, standards) which specify such rules.
