U+FF49 "ｉ" Fullwidth Latin Small Letter I Unicode Character
Unicode Version 17.0
ｉ
U+FF49 "ｉ" Fullwidth Latin Small Letter I is a typographic variant of the standard Latin small letter "i", designed to occupy the same width as a CJK (Chinese, Japanese, and Korean) character in East Asian text environments. Unlike the regular "i" which is proportionally spaced, this fullwidth version is monospaced and square shaped, allowing it to align perfectly with other fullwidth characters in vertical or horizontal writing. It is commonly used in contexts where visual consistency is important, such as in Japanese text, computer interfaces, or when mixing Latin letters with ideographic scripts.
