The default string primitive in Go, [50] Julia, Rust, Swift (since version 5), [51] and PyPy [52] uses UTF-8 internally in all cases. Python (since version 3.3) uses UTF-8 internally for Python C API extensions [53] [54] and sometimes for strings [53] [55] and a future version of Python is planned to store strings as UTF-8 by default.
So newer software systems are starting to use UTF-8. The default string primitive used in newer programing languages, such as Go, [18] Julia, Rust and Swift 5, [19] assume UTF-8 encoding. PyPy also uses UTF-8 for its strings, [20] and Python is looking into storing all strings with UTF-8. [21] Microsoft now recommends the use of UTF-8 for ...
For example, an ASCII (or extended ASCII) scheme will use a single byte of computer memory, while a UTF-8 scheme will use one or more bytes, depending on the particular character being encoded. Alternative ways to encode character values include specifying an integer value for a code point, such as an ASCII code value or a Unicode code point.
The same character converted to UTF-8 becomes the byte sequence EF BB BF. The Unicode Standard allows the BOM "can serve as a signature for UTF-8 encoded text where the character set is unmarked". [75] Some software developers have adopted it for other encodings, including UTF-8, in an attempt to distinguish UTF-8 from local 8-bit code pages.
Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers.

[citation needed] UTF-8 is a sparse encoding: a large fraction of possible byte combinations do not result in valid UTF-8 text. Binary data and text in any other encoding are likely to contain byte sequences that are invalid as UTF-8, so existence of such invalid sequences indicates the file is not UTF-8, while lack of invalid sequences is 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.
