CJK Unified Ideographs is a Unicode block containing the most common CJK ideographs used in modern Chinese and Japanese.

The block has hundreds of variation sequences defined for standardized variants.[3]

It also has tens of thousands of ideographic variation sequences registered in the Unicode Ideographic Variation Database (IVD).[4][5] These sequences specify the desired glyph variant for a given Unicode character.
