CJK Unified Ideographs Extension D is a Unicode block containing rare and historic CJK ideographs for Chinese, Japanese, Korean, and Vietnamese.

The block has hundreds of ideographic variation sequences registered in the Unicode Ideographic Variation Database (IVD).[3][4] These sequences specify the desired glyph variant for a given Unicode character.
