U+FF41 "ａ" Fullwidth Latin Small Letter A Unicode Character
Unicode Version 17.0
ａ
U+FF41 "ａ" Fullwidth Latin Small Letter A is a variant of the standard Latin letter "a" that occupies the same horizontal space as a Chinese, Japanese, or Korean (CJK) character, making it twice as wide as a typical Western letter. It belongs to the "Halfwidth and Fullwidth Forms" block of Unicode, where fullwidth characters like this one are used in East Asian typography to maintain visual consistency and alignment when mixed with ideographic text. Despite its different shape and spacing, it represents the same basic sound and letter as its halfwidth counterpart, and it encodes the abstract character for the lowercase "a" in a fullwidth presentation form.
