XMLDocument LoadFile with Chinese Characters in path

[Harry Boy]

I'm using TinyXML2 to load an xml document from disk.

The path of the file (configFileName) is a std::wstring and I am converting it to string like so:

tinyxml2::XMLDocument doc;
std::string fileName(configFileName.begin(), configFileName.end());
doc.LoadFile(fileName.c_str());

This works but there may be times where my program runs on a double byte OS such as Chinese or Korean and the conversion from wstring to string above will loose the characters.

How can I load a path such as the following:
wstring wPathChinese = L"C:\我明天要去上海\在这里等我\MyProgram";
