Unicode Block - CJK Unified Ideographs
CJK Unified Ideographs is the core collection of Chinese, Japanese, and Korean characters that encodes the vast majority of shared Han logograms used in traditional and simplified Chinese, as well as in Japanese kanji and Korean hanja. These characters represent a standardized set of ideographs that have been unified across regional variants to avoid duplicate encoding, while preserving subtle shape differences through language-specific glyph variants. The block encompasses a wide range of common and historical characters, including those used in classical texts, modern writing, and personal names, and it forms the foundation for digital text processing in East Asian languages. Its inclusion in modern standards ensures interoperability across platforms and fonts, making it essential for any software or document that handles Chinese, Japanese, or Korean content.
