A binary-to-text encoding is encoding of data in plain text.More precisely, it is an encoding of binary data in a sequence of printable characters.These encodings are necessary for transmission of data when the communication channel does not allow binary data (such as email or NNTP) or is not 8-bit clean.
Input and display software obviously needs to know about the structure of the multibyte encoding scheme, but other software generally doesn't need to know if a pair of bytes represent two separate characters or just one character. For example, the four character string "I♥NY" is encoded in UTF-8 like this (shown as hexadecimal byte values ...

Common examples of character encoding systems include Morse code, the Baudot code, the American Standard Code for Information Interchange (ASCII) and Unicode. Unicode, a well-defined and extensible encoding system, has replaced most earlier character encodings, but the path of code development to the present is fairly well known.
In November 2003, UTF-8 was restricted by RFC 3629 to match the constraints of the UTF-16 character encoding: explicitly prohibiting code points corresponding to the high and low surrogate characters removed more than 3% of the three-byte sequences, and ending at U+10FFFF removed more than 48% of the four-byte sequences and all five- and six ...
A character literal is a type of literal in programming for the representation of a single character's value within the source code of a computer program. Languages that have a dedicated character data type generally include character literals; these include C , C++ , Java , [ 1 ] and Visual Basic . [ 2 ]
Each Unicode code point is encoded either as one or two 16-bit code units. Code points less than 2 16 ("in the BMP") are encoded with a single 16-bit code unit equal to the numerical value of the code point, as in the older UCS-2. Code points greater than or equal to 2 16 ("above the BMP") are encoded using two 16-bit code units.
In computer programming, a naming convention is a set of rules for choosing the character sequence to be used for identifiers which denote variables, types, functions, and other entities in source code and documentation. Reasons for using a naming convention (as opposed to allowing programmers to choose any character sequence) include the ...
