The Braille pattern dots-23 ( ⠆ ) is a 6-dot braille cell with the middle and bottom left dots raised, or an 8-dot braille cell with the two middle-left dots raised.
It is represented by the Unicode code point U+2806, and in Braille ASCII with the number "2".
In unified international braille, the braille pattern dots-23 is used to represent a voiced bilabial consonant, such as /b/ or /ɓ/ when multiple letters correspond to these values, and is otherwise assigned as punctuation or accent mark, as needed.
In the Japanese kantenji braille, the standard 8-dot Braille patterns 37, 137, 347, and 1347 are the patterns related to Braille pattern dots-23, since the two additional dots of kantenji patterns 023, 237, and 0237 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-23 for all 6349 kanji found in JIS C 6226-1978.
