An array of narrow character type ([basic.fundamental]),
char16_t array,
char32_t array,
or wchar_t array
can be initialized by a
narrow string literal, char16_t string literal, char32_t string
literal, or wide string literal,
respectively, or by an appropriately-typed string literal enclosed in
braces ([lex.string]).
Successive
characters of the
value of the string literal
initialize the elements of the array.
