D:\libs\vcpkg\installed\x64-windows\include\indicators/display_width.hpp(281): error C2220: the following warning is t reated as an error D:\libs\vcpkg\installed\x64-windows\include\indicators/display_width.hpp(281): warning C4996: 'std::codecvt_utf8<wchar _t,1114111,0>': warning STL4017: std::wbuffer_convert, std::wstring_convert, and the <codecvt> header (containing std: :codecvt_mode, std::codecvt_utf8, std::codecvt_utf16, and std::codecvt_utf8_utf16) are deprecated in C++17. (The std:: codecvt class template is NOT deprecated.) The C++ Standard doesn't provide equivalent non-deprecated functionality; c onsider using MultiByteToWideChar() and WideCharToMultiByte() from <Windows.h> instead. You can define _SILENCE_CXX17_ CODECVT_HEADER_DEPRECATION_WARNING or _SILENCE_ALL_CXX17_DEPRECATION_WARNINGS to acknowledge that you have received this warning.
also when skip this warnning, release(RelWithDbg) build is not work(debug is ok). here is the call stack:
// my code
bars[idx].set_option(option::PrefixText{"600000.SH"});
// exit with call stack
