CJK Unified Ideographs Extension G is a Unicode block containing rare and historic CJK Unified Ideographs for Chinese, Japanese, Korean, and Vietnamese which were submitted to the Ideographic Research Group during 2015.[3] It is the first block to be allocated to the Tertiary Ideographic Plane.

The exotic characters 𰻞 biáng and 𱁬 taito are present in this block.

The block has three 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.
