The resulting buffer of 3 bytes is then broken in 4 packs of 6 bits each.
Those 6 bits form a number corresponding to the index in the character set supported by Base64 (A-Z, a-z, 0-9, and /).
Early binary repertoires include Bacon's cipher, Braille, International maritime signal flags, and the 4-digit encoding of Chinese characters for a Chinese telegraph code (Hans Schjellerup, 1869).
Common examples of character encoding systems include Morse code, the Baudot code, the American Standard Code for Information Interchange (ASCII) and Unicode.
The low cost of digital representation of data in modern computer systems allows more elaborate character codes (such as Unicode) which represent most of the characters used in many written languages.
Character encoding using internationally accepted standards permits worldwide interchange of text in electronic form.
Still decoder will suggest even partial translations.
Decoder also recognizes most popular email and web encodings like base64, quoted-printable, urlencoded, etc.
Mainly it is due to a possible loss of some encoding information while copying a text.In trying to develop universally interchangeable character encodings, researchers in the 1980s faced the dilemma that on the one hand, it seemed necessary to add more bits to accommodate additional characters, but on the other hand, for the users of the relatively small character set of the Latin alphabet (who still constituted the majority of computer users), those additional bits were a colossal waste of then-scarce and expensive computing resources (as they would always be zeroed out for such users).The compromise solution that was eventually found and developed into Unicode was to break the assumption (dating back to telegraph codes) that each character should always directly correspond to a particular sequence of bits.If the number of bytes are not in numbers of three, then padding is used; == for 1 byte and = for 2 bytes. Listed here are a few examples on how to embed Base64 resources within different web documents. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.
Base64-encoded data takes about 33% more space than the original data.
