the letter L, as in L’x’. A character literal that does not begin with L is an ordinary character literal, also
referred to as a narrowcharacter

in the execution character set.
An ordinary character literal that contains more than one cchar
is a multicharacter literal. A multicharacter
literal has type int and implementationdefined
