About this character

U+FF1A (：) is FULLWIDTH COLON, a punctuation mark in the Halfwidth and Fullwidth Forms block. Its script is Common: it is shared by many writing systems rather than belonging to one. It was added in Unicode 1.1 (1993).

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

Its East Asian Width is Fullwidth, so terminals and monospaced layouts give it two columns.

It has standardized variation sequences that request a specific glyph shape: U+FF1A U+FE00 — corner-justified form; U+FF1A U+FE01 — centered form. See variation selectors.
