 The **char** type was the original character type in C and C++. The type **unsigned char** is often used to represent a *byte*, which is not a built-in type in C++. The **char** type can be used to store characters from the ASCII character set or any of the ISO-8859 character sets, and individual bytes of multi-byte characters such as Shift-JIS or the UTF-8 encoding of the Unicode character set. Strings of **char** type are referred to as *narrow* strings, even when used to encode multi-byte characters. In the Microsoft compiler, **char** is an 8-bit type.
 
-The **wchar_t** type is an implementation-defined wide character type. In the Microsoft compiler, it represents a 16-bit wide character used to store Unicode encoded as UTF-16LE, the native character type on Windows operating systems. The wide character versions of the Universal C Runtime (UCRT) library functions use **wchar_t** and **wchar_t \*** types as parameters and return values, as do the wide character versions of the native Windows API.

 The **char16_t** and **char32_t** types represent 16-bit and 32-bit wide characters, respectively. Unicode encoded as UTF-16 can be stored in the **char16_t** type, and Unicode encoded as UTF-32 can be stored in the **char32_t** type. Strings of these types and **wchar_t** are all referred to as *wide* strings, though the term often refers specifically to strings of **wchar_t** type.
