Can't filename.string() work?

filename.string() may make errors with the pure utf-8 encoded path. Let's consider following:

#include <iostream>
#include <string>
#include <filesystem>

int main(int argc, char* argv[])
{
	try {
		std::filesystem::path fileStr = L"G:\\Tuấn Anh\\tết.txt";
		std::string test1 = fileStr.u8string();
		std::string test2 = fileStr.string(); // >>>>>>>>>>> throw exception
	}
	catch (const std::exception& ex) {
		std::cerr << ex.what() << std::endl;
		return 1;
	}

	return 0;
}

I tried again with filename.string(), the exception was thrown.
With minio::utils::Trim(...), I don't think there is a different in result with filename.string() or filename.u8string()

return error::Error("filename cannot be empty");
}

if (!overwrite && std::filesystem::exists(filename)) {
return error::Error("file " filename " already exists");
return error::Error("file " filename.u8string() " already exists");
}

return error::SUCCESS;
