I think we want hex //and// decimal. ================ Comment at: clang/test/SemaCXX/static-assert.cpp:287 + static_assert((char16_t)L'ゆ' == L"C̵̭̯̠̎͌ͅť̺"[1], ""); // expected-error {{failed}} \ + // expected-note {{evaluates to ''ゆ' (0x3086) == '̵' (0x335)'}} + static_assert(L"\/"[1] == u'\xFFFD', ""); // expected-error {{failed}} \ ---------------- The C++23 escaped string formatting facility would not generate a trailing combining character like this.
