The Braille pattern dots-34 ( ⠌ ) is a 6-dot braille cell with the top right and bottom left dots raised, or an 8-dot braille cell with the top right and lower-middle dots raised.
It is represented by the Unicode code point U+280c, and in Braille ASCII with the slash: /.
In unified international braille, the braille pattern dots-34 is used to represent a front, open to close diphthong, i.e. /ai/, or otherwise assigned as needed.
In the Japanese kantenji braille, the standard 8-dot Braille patterns 57, 157, 457, and 1457 are the patterns related to Braille pattern dots-34, since the two additional dots of kantenji patterns 034, 347, and 0347 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-34 for all 6349 kanji found in JIS C 6226-1978.
