In Unicode, a Private Use Area (PUA) is a range of code points that, by definition, will not be assigned characters by the standard. [1] Three private use areas are defined: one in the Basic Multilingual Plane (U+E000–U+F8FF), and one each in, and nearly covering, planes 15 and 16 (U+F0000–U+FFFFD, U+100000–U+10FFFD).
If a character was punched erroneously, punching out all seven bits caused this position to be ignored or deleted. [2] [3] In hexadecimal, this is 7F to rub out 7 bits (FF to rubout 8 bits was used for 8-bit codes). This character could also be used as padding to slow down printing after newlines, though the all-zero NUL was more often used.
The human aspects of passwords must also be considered. Unlike computers, human users cannot delete one memory and replace it with another. Consequently, frequently changing a memorized password is a strain on the human memory, and most users resort to choosing a password that is relatively easy to guess (See Password fatigue).
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).
A title can normally contain the character %. However it cannot contain % followed by two hexadecimal digits (which would cause it to be converted to a single character, by percent-encoding). Similarly a title cannot contain HTML character entities such as / and –, even if the character they represent is allowed. In the unlikely event ...
A Unicode character is assigned a unique Name (na). [1] The name is composed of uppercase letters A–Z, digits 0–9, hyphen-minus and space.Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed.
Delete means simply that the user thinks the article should be deleted. They may state reasons or simply leave it at this statement. Because the deletion process is a discussion and not a vote, simply stating "delete" without any further comment is discouraged. Keep means simply that the user thinks the article should not be deleted. They may ...
Please remove the speedy deletion tag from the page. Doing so will automatically remove the page from Category:Candidates for speedy deletion. Consider notifying the nominator, using {{speedy-decline}} or {}. (If you're using CSD Helper, it will usually notify the nominator for you; it will normally use its own notification template.)
