U+FF14 "４" Fullwidth Digit Four Unicode Character

U+FF14 "４" Fullwidth Digit Four is a typographic variant of the standard digit "4" that occupies the same width as a Chinese or Japanese character, typically used in East Asian text formatting for alignment in tables, documents, and monospaced contexts where a square or evenly spaced appearance is required. It belongs to the Halfwidth and Fullwidth Forms block in Unicode, which provides fullwidth versions of ASCII digits, letters, and punctuation to accommodate mixed East Asian and Latin text without visual inconsistency. This character is commonly found in Japanese, Chinese, and Korean writing systems, as well as in retro computing environments like old terminals or fixed-width displays that emulate a uniform character grid.
