-          As of version 0.9, there is no function for saving XML document to wide
-          character paths. Unfortunately, there is no portable way to do this; the
-          version 1.0 will provide such function only for platforms with the corresponding
-          functionality. You can use stream-saving functions as a workaround if your
-          STL implementation can open file streams via wchar_t paths.
