+    //  POSIX specfies that path strings are passed unchanged to and from the

+    //  which convert according to a locale.
+    //
+    //  Thus for POSIX, char strings do not undergo conversion.  wchar_t strings
+    //  are converted to/from char using the path locale or, if a conversion
+    //  argument is given, using a conversion object modeled on
+    //  std::wstring_convert.
+    //
+    //  The path locale, which is global to the thread, can be changed by the
+    //  imbue() function. It is initialized to an implementation defined locale.
+    //  
+    //  For Windows, wchar_t strings do not undergo conversion. char strings
+    //  are converted using the "ANSI" or "OEM" code pages, as determined by
+    //  the AreFileApisANSI() function, or, if a conversion argument is given,
+    //  using a conversion object modeled on std::wstring_convert.
