Files that contain machine-executable code and non-textual data typically contain all 256 possible eight-bit byte values. Many computer programs came to rely on this distinction between seven-bit text and eight-bit binary data, and would not function properly if non-ASCII characters appeared in data that was expected to include only ASCII text ...
A second common application of non-breaking spaces is in plain text file formats such as SGML, HTML, TeX and LaTeX, whose rendering engines are programmed to treat sequences of whitespace characters (space, newline, tab, form feed, etc.) as if they were a single character (but this behavior can be overridden).
Because Base64 is a six-bit encoding, and because the decoded values are divided into 8-bit octets, every four characters of Base64-encoded text (4 sextets = 4 × 6 = 24 bits) represents three octets of unencoded text or data (3 octets = 3 × 8 = 24 bits). This means that when the length of the unencoded input is not a multiple of three, the ...
In computing, it is often used for padding in fixed length records; to mark the end of a string; and formerly to give printing devices enough time to execute a control function. Code 127 (DEL, a.k.a. "rubout") is likewise a special case. Its 7-bit code is all-bits-on in binary, which essentially erased a character cell on a paper tape when ...
A whitespace character is a character data element that represents white space when text is rendered for display by a computer.. For example, a space character (U+0020 SPACE, ASCII 32) represents blank space such as a word divider in a Western script.
1 000 000 000 000 (thin space) or 1000000 not 1,000,000 or 1.000.000 1 000 000 000 000 (regular space which is significantly wider) Sometimes a narrow non-breaking space or non-breaking space , respectively, is recommended (as in, for example, IEEE Standards [ 25 ] and IEC standards [ 26 ] ) to avoid the separation of units and values or parts ...
