U+FF21 "Ａ" Fullwidth Latin Capital Letter A Unicode Character
Unicode Version 17.0
U+FF21 "Ａ" Fullwidth Latin Capital Letter A is a variant of the standard Latin capital letter A that occupies the same width as a CJK ideographic character, typically two bytes or a full square space, as opposed to the halfwidth form used in typical Latin text. It belongs to the "Halfwidth and Fullwidth Forms" Unicode block, a range of characters designed to maintain visual consistency in East Asian typography, where fullwidth glyphs are used alongside Chinese, Japanese, or Korean script. This character is visually identical in shape to the regular capital A but is encoded separately to support specific layout requirements in monospaced or mixed-script environments. Its primary use is in text that requires alignment in a grid or when representing Latin letters within fullwidth text contexts, such as in certain terminal displays, old computer systems, or formatted documents.
