CJK Compatibility Ideographs is a Unicode block created to contain Han characters that were encoded in multiple locations in other established character encodings, in addition to their CJK Unified Ideographs assignments, in order to retain round-trip compatibility between Unicode and those encodings. Such encodings include:

South Korean KS X 1001:1998 (U+F900–U+FA0B, 268 characters)
Taiwanese Big5 (U+FA0C–U+FA0D, 2 characters)
Japanese IBM 32 (CP932 variant; U+FA0E–U+FA2D, 32 characters, 12 are unified)
South Korean KS X 1001:2004 (U+FA2E–U+FA2F, 2 character)
Japanese JIS X 0213 (U+FA30–U+FA6A, 59 characters)
Japanese ARIB STD-B24 (U+FA6B–U+FA6D, 3 characters)
North Korean KPS 10721-2000 (U+FA70–U+FAD9, 106 characters)

In ensuing versions of the standard, more characters have been added to the block. These even include a few regular ideographs (with the Unified_Ideograph property) that are not found in the CJK Unified Ideographs block.[4] As of now, all the regular ideographs are from the IBM 32 source. The IBM 32 encoding already contained duplicates warranting the need to encode the duplicates in this block, but also included twelve rare kokuji characters. These are are:

FA0E..FA0F
FA11
FA13..FA14
FA1F
FA21
FA23..FA24
FA27..FA29
蘒 (FA20) is considered equivalent to 蘒 (8612), but might also be treated as unified (such as Source Han Sans).

The block has dozens of ideographic variation sequences registered in the Unicode Ideographic Variation Database (IVD).[5][6] These sequences specify the desired glyph variant for a given Unicode character.
