U+30C3 "ッ" Katakana Letter Small Tu Unicode Character

U+30C3 "ッ" Katakana Letter Small Tu is a typographic symbol from the Japanese katakana syllabary used primarily to indicate a geminate or double consonant in the pronunciation of a word. This small form of the standard katakana character "ツ" (tsu) is not pronounced as a syllable itself but instead signals that the following consonant sound should be lengthened or enunciated with a brief pause, such as in the word "マッチ" (matchi) for "match". It is a fundamental component of Japanese orthography, appearing in loanwords, onomatopoeia, and emphatic speech to convey a sharp, clipped phonetic effect.
