U+FF3A "Ｚ" Fullwidth Latin Capital Letter Z Unicode Character

U+FF3A "Ｚ" Fullwidth Latin Capital Letter Z is a variant of the standard Latin letter Z designed to occupy the same amount of horizontal space as CJK (Chinese, Japanese, and Korean) characters, typically used in East Asian typography for monospaced alignment, mathematical notation, or stylistic emphasis within mixed-script text. Unlike its halfwidth counterpart, which fits into a narrower cell, the fullwidth version is rendered as a square glyph, matching the width of ideographic characters in fonts that support the fullwidth block.
