CJK Unified Ideographs Extension-A is a Unicode block containing rare Han ideographs.

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

It also has 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.
