Braille ASCII (or more formally The North American Braille ASCII Code, also known as SimBraille) is a subset of the ASCII character set which uses 64 of the printable ASCII characters to represent all possible dot combinations in six-dot braille. It was developed around 1969 and, despite originally being known as North American Braille ASCII ...
The Unicode block Braille Patterns (U+2800..U+28FF) contains all 256 possible patterns of an 8-dot braille cell, thereby including the complete 6-dot cell range. [3] In Unicode, a braille cell does not have a letter or meaning defined.
The Braille pattern dots-0 ( ⠀), also called a blank Braille pattern, is a 6-dot or 8-dot braille cell with no dots raised. It is represented by the Unicode code point U+2800, and in Braille ASCII with a space.
Most braille embossers and refreshable braille displays do not use the Unicode code points, but instead reuse the 8-bit code points that are assigned to standard ASCII for braille ASCII. (Thus, for simple material, the same bitstream may be interpreted equally as visual letter forms for sighted readers or their exact semantic equivalent in ...
It is virtually identical to Braille ASCII, a system of representation of braille with ASCII characters, which goal is mirrored to the Computer Braille Code. To represent ASCII code points 0x60, 0x7B, 0x7C, 0x7D, 0x7E as well as capital letters the 4-5-6 ( ⠸ ) character is used as the shift indicator or modifier.
The Braille pattern dots-3456 ( ⠼) is a 6-dot braille cell with the top right, middle right, and both bottom dots raised, or an 8-dot braille cell with the top right, upper-middle right, and both lower-middle dots raised. It is represented by the Unicode code point U+283c, and in Braille ASCII with a number sign: #.
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: *.
The Braille pattern dots-35 ( ⠔) is a 6-dot braille cell with the bottom left and middle right dots raised, or an 8-dot braille cell with the lower-middle left and upper-middle right dots raised. It is represented by the Unicode code point U+2814, and in Braille ASCII with the number 9.
