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.
Unicode uses the standard dot-numbering 1 to 8. Historically only the 6-dot cell was used in braille. The lower two dots were added later, which explains the irregular numbering 1-2-3-7 in the left column and 4-5-6-8 in the right column. Where dots 7 and 8 are not raised, there is no distinction between 6-dot and 8-dot definitions.
A vertical service code (VSC) is a sequence of digits and the signals star (*) and pound/hash (#) dialed on a telephone keypad or rotary dial to access certain telephone service features. [1]
In some cases, spaces are shown simply as blank space; in other cases they may be represented by an interpunct or other symbols. Many different characters (described below) could be used to produce spaces, and non-character functions (such as margins and tab settings) can also affect whitespace.
The Braille pattern dots-34 ( ⠌) is a 6-dot braille cell with the top right and bottom left dots raised, or an 8-dot braille cell with the top right and lower-middle dots raised. It is represented by the Unicode code point U+280c, and in Braille ASCII with the slash: /.
In 6-dot notation there are 64 combinations, in 8-dot notation this number is 256 (including all 6-dot cells). Such a definition is independent of the braille language (there is no connection with a letter A; this is for the Braille language to add). Using the cell numbering shown here, one can simply mention the raised dots: say dots-1234 for ⠏.
