U+F947 "磊" CJK Compatibility Ideograph-# Unicode Character

Unicode Version 17.0

U+F947 "磊" CJK Compatibility Ideograph-# is a compatibility ideograph used in the Unicode Standard to represent a special variant or simplified form of the Chinese character for "seven" (七), primarily for roundtrip mapping with legacy East Asian character encoding standards such as Shift JIS. This character is categorized under the CJK Compatibility Ideographs block, which was created to encode characters that were unified with other ideographs in the main CJK Unified Ideographs block but needed distinct code points to preserve lossless data conversion from older character sets. As a compatibility character, its use is generally discouraged in modern text unless interoperability with legacy systems is required, and it should not be confused with the standard CJK Unified Ideograph for "seven" (U+4E03).
