The default string primitive in Go, [49] Julia, Rust, Swift (since version 5), [50] and PyPy [51] uses UTF-8 internally in all cases. Python (since version 3.3) uses UTF-8 internally for Python C API extensions [52] [53] and sometimes for strings [52] [54] and a future version of Python is planned to store strings as UTF-8 by default.

(July 2019) (Learn how and when to remove this message) This article compares Unicode encodings in two types of environments: 8-bit clean environments, and environments that forbid the use of byte values with the ...
Thus, the number of code units required to represent a code point depends on the encoding: UTF-8: code points map to a sequence of one, two, three or four code units. UTF-16: code units are twice as long as 8-bit code units. Therefore, any code point with a scalar value less than U+10000 is encoded with a single code unit.
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". [74] 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.
The default string primitive used in newer programing languages, such as Go, [22] Julia, Rust and Swift 5, [23] assume UTF-8 encoding. PyPy is also using UTF-8 for its strings, [24] and Python is looking into storing all strings with UTF-8. [25] Microsoft now recommends the use of UTF-8 for applications using the Windows API, while continuing ...

The Unicode Standard permits the BOM in UTF-8, [4] but does not require or recommend its use. [5] UTF-8 always has the same byte order, [6] so its only use in UTF-8 is to signal at the start that the text stream is encoded in UTF-8, or that it was converted to UTF-8 from a stream that contained an optional BOM. The standard also does not ...
