Description
Describe the bug
When I invoke std::filesystem::path::generic_string, the VS gets into the debug mode, and it shows that the std::string object can not be converted into wide. I find the std::filesystem::_Check_convert_result return zero at that time. Then I try to use setlocale(LC_ALL, "zh-CN.UTF-8"); to solve the problem. However, this problem occupies again but not the same place, this time it happens when I try to construct a path by the string. It seems that it also can not covert the string correctly.
STL version (git commit or Visual Studio version):latest VS2017

Research direction
Start by reproducing the failure in VS2017 using std::filesystem::path::generic_string and path construction from a string under the reported Chinese environment. Inspect the conversion path around std::filesystem::_Check_convert_result and compare behavior with setlocale(LC_ALL, "zh-CN.UTF-8"); done means both reported conversions work without entering the debugger.
