You can write and compile your code snippets on your PC, tablet or mobile device. } Another person standing a great distance away can interpret the flags and reproduce the words sent. Character encodings may be broadly grouped according to the number of bytes required to represent a single character: there are single byte encodings, multibyte (also called wide) encodings, and variable-width (also called variable-length) encodings.

In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium. [2], System of rules to convert information into another form or representation, "Encoding" redirects here. Variable-length codes are especially useful when clear text characters have different probabilities; see also entropy encoding. Using the extension of the code, the encoded string 0011001011 can be grouped into codewords as 0 011 0 01 011, and these in turn can be decoded to the sequence of source symbols acabc.

Virtually any uniquely decodable one-to-many code, not necessary a prefix one, must satisfy Kraft's inequality. One reason for coding is to enable communication in places where ordinary plain language, spoken or written, is difficult or impossible. Early multibyte encodings were fixed-length, meaning that although each character was represented by more than one byte, all characters used the same number of bytes ("word length"), making them suitable for decoding with a lookup table.
