적용 범위

This standard applies to the processing, exchange, storage, and transmission of Chinese and other graphic character information. It is mandatory for technical products with Chinese information processing capabilities, including software like OCR and machine translation, as well as hardware like communication terminals and e-readers. Manufacturers of IT equipment entering the Chinese market must ensure compliance with this coding standard.

기술 요구 사항

GB 18030-2022 specifies the graphic characters and their hexadecimal binary representations for information technology. The standard defines a comprehensive character repertoire organized into single-byte, double-byte, and four-byte encoding structures. The double-byte section incorporates characters from GB/T 2312-1980 and CJK Unified Ideographs, while the four-byte section significantly expands the character set. This includes additions for CJK Unified Ideographs Extensions C through F, Kangxi radicals, and various ethnic minority scripts such as New Tai Lue, Lisu, and Miao. Compared to the previous 2005 version, this update modifies specific code positions for vertical punctuation and Han character components, while removing duplicate encodings. Implementers must adhere to the newly added implementation levels chapter to verify system compliance. The standard also introduces a normative annex detailing ideographic description characters.

시험 방법

As a coding standard, GB 18030-2022 does not involve physical laboratory testing. Instead, compliance is verified through software validation and character mapping checks against the specified code tables. Engineers must ensure their systems correctly parse single-byte, double-byte, and four-byte structures as defined in the normative annexes. Verification includes checking the accurate rendering of CJK extensions and minority scripts.
