- We propose additional encodings for literals that can now appear in signatures. nullptr is "LDn0E"; i.e., "a zero of type std::nullptr_t". More interestingly, string literals are encoded as L<character type>E, where<character type> is the encoding of the (unqualified) underlying character type. This has a few consequences for the demangler: It cannot actually reproduce the string, and it can only distinguish character literals from string literals after having seen the first character following the character type code.
Is this sufficient? Overloading can be dependent on the length of the string, i.e. these are different templates:
template<class T> auto foo(T x) -> decltype(bar(x, "abc"));
template<class T> auto foo(T x) -> decltype(bar(x, "abcd"));
