About this character

U+2A74 (⩴) is DOUBLE COLON EQUAL, a mathematical symbol in the Supplemental Mathematical Operators block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 3.2 (2002).

It is a compatibility variant of U+003A : + U+003A : + U+003D = (compatibility decomposition <compat>). NFC and NFD leave it alone, but NFKC and NFKD replace it with U+003A : + U+003A : + U+003D =. Search engines, identifier checks and username systems that apply NFKC will treat the two as the same text.

It is a mirrored character: in right-to-left text renderers draw its mirror image.
