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.
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 was added that is meant to store UTF-8 characters and the types of u8 prefixed character and string literals were changed to char8_t and char8_t ...
Many Unicode characters are used to control the interpretation or display of text, but these characters themselves have no visual or spatial representation. For example, the null character (U+0000 NULL) is used in C-programming application environments to indicate the end of a string of characters.
C++11 also added new string literals of 16-bit and 32-bit "characters" and syntax for putting Unicode code points into null-terminated (C-style) strings. [15] A basic_string is guaranteed to be specializable for any type with a char_traits struct to accompany it.
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.
The C1 Controls and Latin-1 Supplement block has been included in its present form, with the same character repertoire since version 1.0 of the Unicode Standard. [3] Its block name in Unicode 1.0 was simply Latin1 .
A character literal is a type of literal in programming for the representation of a single character's value within the source code of a computer program. Languages that have a dedicated character data type generally include character literals; these include C , C++ , Java , [ 1 ] and Visual Basic . [ 2 ]
UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode Transformation Format – 8-bit. [1] Almost every webpage is stored in UTF-8.
