The current implementation for MinGWX64 relies on the _stat64 function. This function expects a char* string encoded in the current system's ANSI code page.

However, the Path object in this library is UTF-8 encoded.

When _stat64 receives UTF-8 bytes in a GBK environment, it misinterprets the characters, leading to "File Not Found" errors.

Replace the usage of _stat64 with its wide-character counterpart: _wstat64. The path should be converted from UTF-8 to UTF-16 (Wide String) before being passed to _wstat64. This will ensure full Unicode support regardless of the user's system locale settings.
