U+FF2D "Ｍ" Fullwidth Latin Capital Letter M Unicode Character

U+FF2D "Ｍ" Fullwidth Latin Capital Letter M is a typographic variant of the standard Latin capital letter M, designed to occupy the exact same width as a CJK (Chinese, Japanese, and Korean) ideographic character, typically twice the width of a normal Latin letter. This fullwidth form is part of the Halfwidth and Fullwidth Forms block in Unicode, and it is commonly used in East Asian text environments for visual consistency, particularly when mixing Latin letters with ideographic scripts or in monospaced contexts like terminal displays. It preserves the same shape and meaning as the regular uppercase M but appears wider and more balanced when aligned with fullwidth punctuation or other characters.
