Yu (hiragana: ãÂÂ, katakana: ã¦) is one of the Japanese kana, which each represents one mora. Both the hiragana and katakana forms are written in two strokes and represent the sound .
When small and preceded by an -i kana, this kana represents a palatalization of the preceding consonant sound with the vowel (see yà Âon).
The yà Âon characters ã and ãÂÂ¥ are encoded in Japanese Braille by prefixing "-u" kana (e.g. Ku, Su) with a yà Âon braille indicator, which can be combined with the "Dakuten" or "Handakuten" braille indicators for the appropriate consonant sounds.
