U+FF6F "ｯ" Halfwidth Katakana Letter Small Tu Unicode Character

U+FF6F "ｯ" Halfwidth Katakana Letter Small Tu is a typographic variant of the standard katakana character "ツ" (tsu), but reduced in size and presented in a halfwidth form, meaning it occupies half the width of a typical fullwidth character. This small version is used in Japanese writing to indicate a geminate or doubled consonant, where it functions as a sokuon that pauses the sound of the following consonant rather than representing a full vowel sound. Its halfwidth design was originally developed for compatibility with older computer systems and display environments that used a limited character grid, allowing it to fit neatly into monospaced text alongside Latin and other halfwidth characters.
