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 ...
The first character of the ls display indicates the file type and is not related to permissions. The remaining nine characters are in three sets, each representing a class of permissions as three characters. The first set represents the user class. The second set represents the group class. The third set represents the others class.
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).
The delete control character (also called DEL or rubout) is the last character in the ASCII repertoire, with the code 127. [1] It is supposed to do nothing and was designed to erase incorrect characters on paper tape. It is denoted as ^? in caret notation and is U+007F in Unicode.
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).
The first character of the ls -l display denotes the object type; a hyphen represents a plain file. The script findPhoneNumbers.sh can be read, written to, and executed by the user dgerman; read and executed by members of the staff group; and only read by any other users. The main parts of the chmod permissions:
The table on the right is an aid for converting between plaintext and ciphertext using the characters at left as the key. In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked. It requires the use of a single-use pre-shared key that is larger than or equal to the size of the message being sent.
The resulting string is encoded using a variant of Base64 (+/ and with padding). The authorization method and a space character (e.g. "Basic ") is then prepended to the encoded string. For example, if the browser uses Aladdin as the username and open sesame as the password, then the field's value is the Base64 encoding of Aladdin:open sesame ...
