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 ...
ASCII (/ ˈ æ s k iː / ⓘ ASS-kee), [3]: 6 an acronym for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. . ASCII codes represent text in computers, telecommunications equipment, and other devic
The 8-dot code is designed that its 6-dot subset is identical to the 6-dot code. The remainder are assigned by the following rules: adding dot 7 subtracts 32 from the ASCII value; adding dot 8 adds 128 to the ASCII value; The dot-5 (⠐) character is used as a universal modifier [clarification needed].
This is simply the ASCII character codes from 32 to 95 coded as 0 to 63 by subtracting 32 (i.e., columns 2, 3, 4, and 5 of the ASCII table (16 characters to a column), shifted to columns 0 through 3, by subtracting 2 from the high bits); it includes the space, punctuation characters, numbers, and capital letters, but no control characters.
The 33 characters classified as ASCII Punctuation & Symbols are also sometimes referred to as ASCII special ... Latin Capital Letter S with dot below and dot above U+ ...
Braille dot numbering Hexadecimal value of braille dots. The coding is in accordance with ISO/TR 11548-1 Communication aids for blind persons. [3] Unicode uses the standard dot-numbering 1 to 8. Historically only the 6-dot cell was used in braille.
The data message in DotCode is represented with data codewords from 0 to 112 which are encoded with 5-of-9 binary dot patterns. DotCode supports the following features: [2]: 5.2.1 Natively encodes digits or ASCII charset (between 0 and 127) with A, B and C code sets and extended ASCII values (128 to 255) with Upper Shift;
