Halfwidth Katakana Letter Small Tu Letter Meaning

ッ is Unicode character “HALFWIDTH KATAKANA LETTER SMALL TU” with codepoint U+FF6F. In Japanese writing, the small “tu” is used to show a geminated consonant (a brief pause/stop before the next sound). In romanization this is often written with a doubled consonant, such as “tt” or “pp”, depending on the following character (for example, in words like “kitte” or “appu”, where the consonant is held briefly). As a halfwidth katakana character, it is typically used in contexts that expect halfwidth kana or legacy encoding patterns. It is not the same as the fullwidth small “tu”.
