Katakana-hiragana Semi-voiced Sound Mark Letter Meaning
゜ (U+309C) is the Katakana-Hiragana Semi-Voiced Sound Mark. It is used as a diacritic-like mark in Japanese to create a semi-voiced sound when attached to certain hiragana or katakana characters (most commonly in the same written word context). It’s distinct from other Japanese marks used for full voicing or lengthening, and it’s typically treated as part of the character sequence rather than standalone punctuation. When copying or rendering, pay attention to font support so the mark displays correctly and stays aligned with the preceding kana.
