U+30FE "ヾ" Katakana Voiced Iteration Mark Unicode Character

U+30FE "ヾ" Katakana Voiced Iteration Mark is a typographic symbol used in the Japanese writing system to indicate the repetition of a previous katakana character while also adding a voiced or "dakuon" sound, such as turning "k" into "g" or "s" into "z". Unlike the unvoiced iteration mark, this mark appears with two small dots resembling a dakuten, and it is typically written smaller than standard characters. It is employed in specific contexts like rendering repeated syllables in names, onomatopoeia, or certain colloquial representations, though it is less common than its hiragana counterpart. Its proper usage requires that it follow a single katakana character within a word, and it cannot stand alone or begin a word.
