Other Forms of String Literals

C++, recall, has the wchar_t type in addition to char. And C++11 adds the char16_t and char32_t types. It’s possible to create arrays of these types and string literals of these types. C++ uses the L, u, and U prefixes, respectively, for string literals of these types. Here’s an example of how they can be used:

wchar_t title[] = L"Chief Astrogator";  // w_char stringchar16_t name[] = u"Felonia Ripova";    // char_16 stringchar32_t car[] = U"Humber Super Snipe"; // char_32 string

C++11 also supports an encoding scheme for Unicode characters called UTF-8. In this scheme a given character may be stored in anywhere from one 8-bit unit, or octet, to four 8-bit units, depending on the numeric value. C++ uses the u8 prefix ...
