These tests are very tricky - in general -fshort-wchar is a dangerous option because, since the standard library is not compiled with it, you can't use any functions from either C or C++ standard library without getting ABI mismatch. The reason we want to use this is to do coverage testing on UTF32->UTF16 and UTF16->UTF32 conversion paths, that generally aren't hit on gcc/clang. To do this, we carefully work around any internal calls to wcslen/wcscmp that pugixml might be doing and don't use any wstring functions.
