This example shows the size of a wide string literal in bytes: Notice that strlen() and wcslen() don't include the size of the terminating null character, whose size is equal to the element size of the string type: one byte on a char* or char8_t* string, two bytes on wchar_t* or char16_t* strings, and four bytes on char32_t* strings.
