Although the current version of Python requires an option to open() to read/write UTF-8, [46] plans exist to make UTF-8 I/O the default in Python 3.15. [47] C++23 adopts UTF-8 as the only portable source code file format. [48] Backwards compatibility is a serious impediment to changing code and APIs using UTF-16 to use UTF-8, but this is happening.

Unicode, in the form of UTF-8, has been the most common encoding for the World Wide Web since 2008. [76] It has near-universal adoption, and much of the non-UTF-8 content is found in other Unicode encodings, e.g. UTF-16. As of 2024, UTF-8 accounts for on average 98.3% of all web pages (and 983 of the top 1,000 highest-ranked web pages). [77]

(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 ...
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 UTF-8, the BOM is optional, while it is a must for the UTF-16 and the UTF-32 encodings. (Note: UTF-16 and UTF-32 without the BOM are formally known under different names, they are different encodings, and thus needs some form of encoding declaration – see UTF-16BE, UTF-16LE, UTF-32LE and UTF-32BE.) The use of the BOM character (U+FEFF ...
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.

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 ...
