- Make ImWchar32 unsigned. - Fix Win32 version of ImFileOpen by including windows.h sooner. - Make ImGuiIO::AddInputCharacterUTF16() more robust by disallowing illegal surrogate pairs. - Allow pushing higher plane codepoints through ImGuiIO::AddInputCharacter(). - Minor cleaning up in the high-plane Unicode support. - Fix Clang -Wunreachable-code warning
