U+FF7A "コ" Halfwidth Katakana Letter Ko Unicode Character

Unicode Version 17.0

U+FF7A "コ" Halfwidth Katakana Letter Ko is a typographic variant of the standard fullwidth Katakana character コ, which represents the Japanese mora "ko" and is part of the Japanese writing system. It belongs to the halfwidth form block in Unicode, designed for compatibility with older computer systems and text formats that required a fixed character width, such as terminal displays or early digital text. This halfwidth version occupies a single character cell horizontally, unlike its fullwidth counterpart, making it useful in certain legacy contexts like CJK (Chinese, Japanese, and Korean) character encoding or for aligning text in monospaced environments.
