Although the current version of Python requires an option to open() to read/write UTF-8, [45] plans exist to make UTF-8 I/O the default in Python 3.15. [46] C++23 adopts UTF-8 as the only portable source code file format. [47] Backwards compatibility is a serious impediment to changing code and APIs using UTF-16 to use UTF-8, but this is happening.
This distinction has been deprecated since Python 3.3, which introduced a flexibly-sized UCS1/2/4 storage for strings and formally aliased Py_UNICODE to wchar_t. [8] Since Python 3.12 use of wchar_t, i.e. the Py_UNICODE typedef, for Python strings (wstr in implementation) has been dropped and still as before an "UTF-8 representation is created ...
Future ICU 75 planned for April 2024 will require C++17 (up from C++11) or C11 (up from C99), depending on what languages is used. ICU has historically used UTF-16 , and still does only for Java; while for C/C++ UTF-8 is supported, [ 5 ] [ 6 ] including the correct handling of "illegal UTF-8".
Some compilers or editors will require entering all non-ASCII characters as \xNN sequences for each byte of UTF-8, and/or \uNNNN for each word of UTF-16. Since C11 (and C++11), a new literal prefix u8 is available that guarantees UTF-8 for a bytestring literal, as in char foo [512] = u8 "φωωβαρ";. [7] Since C++20 and C23, a char8_t type ...
C++11 allows raw strings, unicode strings (UTF-8, UTF-16, and UTF-32), and wide character strings, determined by prefixes. It also adds literals for the existing C++ string, which is generally preferred to the existing C-style strings. In Tcl, brace-delimited strings are literal, while quote-delimited strings have escaping and interpolation.
Legacy programs can generally handle UTF-8 encoded files, even if they contain non-ASCII characters. For instance, the C printf function can print a UTF-8 string because it only looks for the ASCII '%' character to define a formatting string. All other bytes are printed unchanged.
Note that for variable-length encodings such as UTF-8, UTF-16 or Shift-JIS, it can be necessary to remove string positions at the end, in order to avoid invalid strings. Format Languages
Modern implementations often use the extensive repertoire defined by Unicode along with a variety of complex encodings such as UTF-8 and UTF-16. 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 ...
