The problem that the third-party library does not support Chinese Characters in windows

1. In mac environments, since the mac file opening function originally supports utf8 character paths, you can directly input Chinese characters without modifying the third-party library code.
2. Because windows functions do not support utf8 characters, you need to modify the third-party library code.
Modification method:
1. Find all the places where fopen is used in the third-party library. If these files reference the same file, you can add a macro to the file to replace fopen (). The Code is as follows:

. H

#ifdef _WIN32std::wstring Utf8ToUnicode(const char* buf);#define fopen(a, b) _wfopen(Utf8ToUnicode(a).c_str(), Utf8ToUnicode(b).c_str())#endif

. Cpp

#ifdef _WIN32#include <Windows.h>#include <vector>std::wstring Utf8ToUnicode(const char* buf){    int len = ::MultiByteToWideChar(CP_UTF8, 0, buf, -1, NULL, 0);    if (len == 0)     {        return L"";    }    std::vector<wchar_t> unicode(len);    ::MultiByteToWideChar(CP_UTF8, 0, buf, -1, &unicode[0], len);    return &unicode[0];}#endif
