Questions tagged [wchar-t]

`wchar_t` is a fundamental data type in the C and C++ programming languages, and it stands for "wide character". Its intended use is to hold any character value from "the system's character set".

wchar_t is the fundamental "wide character" data type in the C and C++ programming languages. Both language standards are intentionally vague on what it is for, specifying only that it can hold any character value "from the system's character set". There are conversion functions to and from the system's narrow, multibyte character encoding, a concept left equally vague (the functions are mbtowc() and wctomb()).

The fact that the C and C++ language standards are at once encoding-agnostic yet also provide for a way to represent an extended character set is the source of much confusion for people who expect explicit guarantees of certain fixed encodings (such as UTF-8 or UTF-32).

The practical use of the wchar_t type is considered debatable by some programmers.
