It's not specifically an extension - it's a multiple byte character. The 
literal 'riffraff' would form a long-long (on some architures), containing 
those ASCII codes all packed into its bits.

That's why the compiler ignores any trailing characters that don't fit into 
its integer type, then issues a bizarre complain't about converting an 
integer to a pointer. "" decays to a pointer.
