The Unicode names of braille dot patterns are not the same as what many English speakers would use colloquially. In particular, Unicode names use the word dots in the plural even when only one dot is listed: thus Unicode says braille pattern dots-5 when most English-speaking users of braille would simply say "braille dot 5" or just "dot 5".
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 Braille set was added to the Unicode Standard in version 3.0 (1999). 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.
A braille translator is a software program that translates electronic text (such as an MS-Word file) into braille and sends it to a braille peripheral, such as a braille embosser (which produces a hard copy of the newly created braille). Typically, each language needs its own braille translator.
The Braille pattern dots-2345 ( ⠞) is a 6-dot braille cell with the top right, both middle, and bottom left dots raised, or an 8-dot braille cell with the top right, both upper-middle, and the lower-middle left dots raised. It is represented by the Unicode code point U+281e, and in Braille ASCII with T.
The Braille pattern dots-345 ( ⠜) is a 6-dot braille cell with the top and middle right and bottom left dots raised, or an 8-dot braille cell with the top and upper-middle right, and lower-middle left dots raised. It is represented by the Unicode code point U+281c, and in Braille ASCII with the greater-than sign: >.
In all braille systems, the braille pattern dots-0 is used to represent a space or the lack of content. [1] In particular some fonts display the character as a fixed-width blank. However, the Unicode standard explicitly states that it does not act as a space, [ 2 ] a statement added in response to a comment that it should be treated as a space.
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: *.
