It was developed around 1969 and, despite originally being known as North American Braille ASCII, it is now used internationally.Overview[edit]Braille ASCII uses the 64 ASCII characters between 32 and 95 inclusive.  All capital letters in ASCII correspond to their equivalent values in uncontracted English Braille.  Note however that, unlike standard print, there is only one braille symbol for each letter of the alphabet. Therefore, in Braille, all letters are lower-case by default, unless preceded by a capitalization sign (\u2820 dot 6).The numbers 1 through 9 and 0 correspond to the letters a through j, except that they are lowered or shifted lower in the Braille cell.  For example, \u2809 dots 1-4 represents c, and \u2812 dots 2-5 is 3.  The other symbols may or may not correspond to their Braille values.  For example, \u280c dots 3-4 represents \/ in Braille ASCII, and this is the Braille slash, but \u283f dots 1-2-3-4-5-6 represents =, and this is not the equals sign in Braille.Braille ASCII more closely corresponds to the Nemeth Braille Code for mathematics than it does to the English Literary Braille Code, as the Nemeth Braille code is what it was originally based upon.If Braille ASCII is viewed in a word processor, it will look like a jumbled mix of letters, numbers, and punctuation. However, there are several fonts available, many of them free, which allow the user to view and print Braille ASCII as simulated braille, i.e. a graphical representation of braille characters.Braille ASCII was originally designed to be a means for storing and transmitting six-dot Braille in a digital format, and this continues to be its primary usage today.  Because it uses standard characters available on computer keyboards, it can be easily typed and edited with a standard word processor.  Many Braille embossers receive their input in Braille ASCII, and nearly all Braille translation software can import and export this format.Most institutions which produce Braille materials distribute BRF files.  BRF is a file that can represent contracted or uncontracted (i.e. grade 1 or grade 2) Unified English Braille, English Braille and non-English languages.[1] BRF files contain plain Braille ASCII plus spaces, Carriage Return, Line Feed, and Form Feed ASCII control characters.  The spaces, Carriage Returns, Line Feeds, and Form feeds are sufficient to specify how the Braille is formatted.  Previously BRF contained some additional specialized formatting instructions, but now BRF is formatted exactly like Web-Braille\/BARD.[2][3] BRF files can  be embossed with a braille embosser or printed, read on a refreshable braille display, or imperfectly back-translated[4] into standard text[5][6] which can then be read by a screen reader or other similar program.  Many find BRF files to be a more convenient way to receive brailled content, and it has increasing use as a distribution format.[7] If a SimBraille font[8] is downloaded and installed a BRF file can be opened in WordPad, Apache Open Office, Microsoft Word, Apple Pages, etc., and the Braille will appear correctly rendered as 2 dimensional, non-tactile, visual 6 dot braille characters when the font is set to SimBraille.Unicode includes a means for encoding eight-dot braille; however, Braille ASCII continues to be the preferred format for encoding six-dot braille.Braille ASCII values[edit]The following table shows the arrangement of characters, with the hexadecimal value, corresponding ASCII character, binary notation matching the standard dot order, Braille Unicode glyph, and general meaning (the actual meaning may change depending on context).[9][10]The following C string literal (which can also be used in Python and other programming languages that accept C string literals) is derived from the above table and gives the Braille ASCII mappings for Unicode Braille characters U+2800 through U+283F in order, starting with U+2800 at the start of the string:\" A1B'K2L@CIF\/MSP\"E3H9O6R^DJG>NTQ,*5"},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/2014\/09\/25\/braille-ascii-wikipedia\/#breadcrumbitem","name":"Braille ASCII – Wikipedia"}}]}]
