The Braille pattern dots-16 ( ⠡ ) is a 6-dot braille cell with the top left and bottom right dots raised, or an 8-dot braille cell with the top left and lower-middle right dots raised.
It is represented by the Unicode code point U+2821, and in Braille ASCII with the asterisk: *.
In unified international braille, the braille pattern dots-16 is used to represent the unvoiced alveolar or palatal affricate, such as /tʃ/ or /tɕ/, or otherwise as needed.
In the Japanese kantenji braille, the standard 8-dot Braille patterns 28, 128, 248, and 1248 are the patterns related to Braille pattern dots-16, since the two additional dots of kantenji patterns 016, 167, and 0167 are placed above the base 6-dot cell, instead of below, as in standard 8-dot braille.
This listing includes kantenji using Braille pattern dots-16 for all 6349 kanji found in JIS C 6226-1978.
