2.6.4 String Literals

New string literals have been introduced to represent UTF-8, UTF-16, UTF-32 strings, as well as raw strings:

const char* utf_8 = u8"Im UTF-8."; 
const char* utf_16 = u"Im UTF-16."; 
const char* utf_32 = U"Im UTF-32."; 
const char* raw = R"_(This text is stored as is, 
line breaks included, 
  spaces included. 
It is thus a four-lines text.)_";
