In HTML and XML, a numeric character reference refers to a character by its Universal Character Set / Unicode code point, and uses the format: &#xhhhh; or. &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form. The hhhh (or nnnn) may be any number of ...
Delimiter. A stylistic depiction of values inside of a so-named comma-separated values (CSV) text file. The commas (shown in red) are used as field delimiters.

Python uses the + operator for string concatenation. Python uses the * operator for duplicating a string a specified number of times. The @ infix operator. It is intended to be used by libraries such as NumPy for matrix multiplication. The syntax :=, called the "walrus operator", was introduced in Python 3.8. It assigns values to variables as ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
First, the web server can include the character encoding or " charset " in the Hypertext Transfer Protocol (HTTP) Content-Type header, which would typically look like this: [1] Content-Type: text/html; charset=utf-8. This method gives the HTTP server a convenient way to alter document's encoding according to content negotiation; certain HTTP ...
String (computer science) Strings are typically made up of characters, and are often used to store human-readable data, such as words or sentences. In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable. The latter may allow its elements to be mutated and the length ...
Zero-width space. The zero-width space (. . ), abbreviated ZWSP, is a non-printing character used in computerized typesetting to indicate word boundaries to text-processing systems for scripts that do not use explicit spacing, or after characters not followed by a visible space after which there may be a line break .
String literal. A string literal or anonymous string [1] is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in x = "foo", where "foo" is a string literal with value foo. Methods such as escape sequences can be ...
