扔掉
MultiByteToWideChar 吧，使用
std::wstring_convert和
std::codecvt_utf8 來處理UTF8與WChar之間的互轉。
VC和Clang都支持哦~
#include <iostream>
#include <string>
#include <locale>
#include <codecvt>
#include <fstream>
int main(int argc, char *argv[])
{
std::wstring str = L"123,我是誰？我愛釣魚島！";
std::wstring_convert<std::codecvt_utf8<wchar_t>> conv;
std::string narrowStr = conv.to_bytes(str);
{
std::ofstream ofs ("c:\\test.txt");
ofs << narrowStr;
}
std::wstring wideStr = conv.from_bytes(narrowStr);
{
std::locale::global(std::locale("Chinese-simplified"));
std::wofstream ofs (L"c:\\testW.txt");
ofs << wideStr;
}
