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 ...
Braille ( / breɪl / BRAYL, French: [bʁɑj]) is a tactile writing system used by people who are visually impaired.

ASCII ( / ˈæskiː / ⓘ 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 devices.
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".
The following table summarizes usage of UTF-8 code units (individual bytes or octets) in a code page format. The upper half is for bytes used only in single-byte codes, so it looks like a normal code page; the lower half is for continuation bytes and leading bytes and is explained further in the legend below.
A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc. For example, a binary string of eight bits (which ...
Unicode, formally The Unicode Standard, [note 1] is a text encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 15.1 of the standard [A] defines 149 813 characters [3] and 161 scripts used in various ordinary, literary, academic, and ...
A binary number is a number expressed in the base -2 numeral system or binary numeral system, a method for representing numbers that uses only two symbols for the natural numbers: typically "0" ( zero) and "1" ( one ). A binary number may also refer to a rational number that has a finite representation in the binary numeral system, that is, the ...
