This happens on the following files:
C:\xsd-build\libxsd-msvc-release\libicuuc-65.1.0+6\libicu/uc\unicode/stringoptions.h(1)
C:\xsd-build\libxsd-msvc-release\libicuuc-65.1.0+6\libicu/uc\unicode/uchar.h(2360)
C:\xsd-build\libxsd-msvc-release\libxerces-c-3.2.3+3\xercesc\util\XMLFloat.cpp(1)
C:\xsd-build\libxsd-msvc-release\libxerces-c-3.2.3+3\xercesc\validators\schema\TraverseSchema.cpp(7687)

I have ever tried to save these files as UTF-16(LE) using Notepad and then
C4819 did not happen. But this is not a regular method.

I really missed step 2.3.  After redo the whole processes, XSD works. Thank
you again.
