wifstream逐字读入中文后输出乱码

Question

#include<iostream>
#include<fstream>
#include<string>
#include <windows.h>
int main()
{
	//locale china("zh_CN.UTF-8");
	//locale::global(locale::global(locale(locale(), "", LC_CTYPE)));
	wcout.imbue(locale("", LC_CTYPE));//将读码格式设置为本地格式
	wchar_t a;
	wstring ss;

	int count[62] = { 0 };
	wifstream read(L"D:/工作/学习/编程/Annabel Lee.txt", ios::in);
	wofstream write(L"D:/工作/学习/编程/Chinese Annabel Lee.txt", ios::trunc);
	if (!read.is_open()) wcout << L"文件读取失败。" << endl;
	if (!write.is_open()) wcout << L"文件输出失败。" << endl;
	write << "不是wofstream有问题，是我有问题。" << endl;
	//while (!read.eof())//可耻地放弃了
	//{
	//	read >> noskipws >> a;
	//	wcout << a;
	//	wcout.clear();//中文字符会导致输出流错误需要重置状态，以防万一加上
	while (getline(read, ss))
	{
		for (size_t i = 0; i < ss.length(); i++)
		{
			a = ss[i];
			wcout << a;
			wcout.clear();
			if (a != ' ') write << a;                        //[哔——]啊，还是乱码
			for (size_t i = 0; i < 26; i++)                  //a~z
				if ((int)a == i + 97)
					count[i]++;
			for (size_t i = 26; i < 52; i++)                 //A~Z
				if ((int)a == i + 39)
					count[i]++;
			if ((int)a > 19967 && (int)a < 40870)            //中文
				count[52]++;
			switch (a)                                       //符号

			}
		}
		wcout << endl;
		write << endl;
	}
	wcout << endl;
	for (size_t i = 0; i < 26; i++)
	{
		wcout << L"有" << count[i] << L"个小写英文字母" << wchar_t(i + 97) << "\t";
		if (i % 3 == 2) wcout << endl;
	}
	wcout << endl;
	for (size_t i = 26; i < 52; i++)
	{
		wcout << L"有" << count[i] << L"个大写英文字母" << wchar_t(i + 39) << "\t";
		if (i % 3 == 1) wcout << endl;
	}
	wcout << endl;
	wcout << L"有" << count[52] << L"个中文" << endl;
	wcout << L"有" << count[53] << L"个空格" << endl;
	wcout << L"有" << count[54] << L"个英文符号" << L"," << endl;
	wcout << L"有" << count[55] << L"个英文符号" << L";" << endl;
	wcout << L"有" << count[56] << L"个英文符号" << L"." << endl;
	wcout << L"有" << count[57] << L"个中文符号" << L"·" << endl;
	wcout << L"有" << count[58] << L"个中文符号" << L"，" << endl;
	wcout << L"有" << count[59] << L"个中文符号" << L"；" << endl;
	wcout << L"有" << count[60] << L"个中文符号" << L"。" << endl;
	wcout << L"有" << count[61] << L"个中文符号" << L"——" << endl;
	read.close();
	write.close();
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), 3);
	wcout << L"readChinese运行结束。" << endl;
	SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), 7);
    return 0;
}

输出结果：英文正常，有关中文计数全部为0，输出全部乱码（原文是英文诗）
