U+FF9E "ﾞ" Halfwidth Katakana Voiced Sound Mark Unicode Character

U+FF9E "ﾞ" Halfwidth Katakana Voiced Sound Mark is a typographic symbol used in Japanese writing to indicate that the preceding katakana character should be pronounced with a voiced sound, such as turning an unvoiced "ka" into a voiced "ga". It is specifically designed for halfwidth katakana characters, which are narrower in width than their fullwidth counterparts and are often used in older computer systems or for limited character display spaces like terminal screens or certain digital text formats. This combining mark is placed after the base character in digital text, functioning similarly to its fullwidth counterpart but occupying only half the width to maintain alignment in monospaced or constrained environments.
