single wchar_t with the value 0x00C0 wchar_t s4[] = L"\u00C0"; // A single wchar_t with the value 0x00C0 A value greater than may be represented by a single if the UTF-32 encoding is used, or two if UTF-16 is used. Importantly, the universal character name always denotes the character "À", regardless of what kind of string literal it is used in, or the encoding in use. The octal and hex escape sequences always denote certain sequences of numerical values, regardless of encoding. Therefore, universal character names are complementary to octal and hex escape sequences; while octal and hex escape sequences represent code units, universal character names represent code points, which may be thought of as "logical" characters.
