At the heart of the program is the interpretation of the source file. You know that it's UTF-8 encoded. That's why the 6 bytes L'﹤' are to be interpreted as 4 Unicode characters.
But how would clang know? It sees 6 bytes, and assumes an 8 bit encoding. Thus, it sees L'xyz' (the precise characters depend on the assumed 8 bit character set).
Clang tells you that it is interpreting L'xyz' as L'x' ignoring y and z. It's extremely unlikely that works as intended.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
