Only a small subset of possible byte strings are error-free UTF-8: several bytes cannot appear; a byte with the high bit set cannot be alone; and in a truly random string a byte with a high bit set has only a 1 ⁄ 15 chance of starting a valid UTF-8 character. This has the (possibly unintended) consequence of making it easy to detect if a ...
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.
This still leaves enough spare 10-bit odd+even coding pairs to allow for at least 12 special non-data characters. The codes that represent the 256 data values are called the data (D) codes. The codes that represent the 12 special non-data characters are called the control (K) codes. All of the codes can be described by stating 3 octal values.
A byte is a bit string containing the number of bits needed to represent a character. On most modern computers, this is an eight bit string. Because the definition of a byte is related to the number of bits composing a character, some older computers have used a different bit length for their byte. [2]
The only literal byte pair left occurs only once, and the encoding might stop here. Alternatively, the process could continue with recursive byte pair encoding, replacing "ZY" with "X": XdXac X=ZY Y=ab Z=aa This data cannot be compressed further by byte pair encoding because there are no pairs of bytes that occur more than once.
5 for an isolated case inside a run of single byte characters. For runs 2 + 2 ⁄ 3 per character plus padding to make it a whole number of bytes plus two to start and finish the run 6 2 + 2 ⁄ 3: 2–6 depending on if the byte values need to be escaped 4–6 for characters inherited from GB2312/GBK (e.g. most Chinese characters) 8 for ...
The byte is a unit of digital information that most commonly consists of eight bits. 1 byte (B) = 8 bits (bit).Historically, the byte was the number of bits used to encode a single character of text in a computer [1] [2] and for this reason it is the smallest addressable unit of memory in many computer architectures.
The term byte string usually indicates a general-purpose string of bytes, rather than strings of only (readable) characters, strings of bits, or such. Byte strings often imply that bytes can take any value and any data can be stored as-is, meaning that there should be no value interpreted as a termination value.
