unicode文本文件 [英] unicode text file
问题描述
我有一些unicode（utf8）文本文件。我_tried_写了一个简单的
程序，读取其中一个并将其写入标准输出但是......
当然它不起作用。有一个简单的方法吗？谢谢，K。
这是我的计划。
#include< fstream>
#include< ; iostream>
#include< string>
using namespace std;
int main（）{
ifstream infile（" in.txt"）;
string s;
while（infile>> s）{
cout<< s;
}
}
I have some unicode (utf8) text file. I _tried_ to write a simple
program that read one of them and write it to the standard output but...
of course it doesn''t work. There is an easy way to do it? Thanks, K.
This is my program.
#include <fstream>
#include <iostream>
#include <string>
using namespace std;
int main(){
ifstream infile ("in.txt");
string s;
while (infile >> s) {
cout << s;
}
}

这是我的程序。
#include< fstream>
#include< iostream>
#include< string> ;
使用命名空间std;
int main（）{
ifstream infile（" in.txt"）;
您应该在尝试阅读之前检查文件是否已成功打开
。
string s;
while（infile>> s）{
cout<< s;
}
}

You should here check that file was opened successfully
before attempting to read from it.
string s;
while (infile >> s) {
cout << s;
}
}
尝试使用''wifstream''和''wcout''。

Try using ''wifstream'' and ''wcout''.

在真正的程序中我当然是这样做的，但在我的帖子里我只放了
必不可少的部分问题。
In the real program of course I do it, but in my post I put only the
essential part of the question.
string s;
while（infile>> s）{
cout<< ; s;
}
}
string s;
while (infile >> s) {
cout << s;
}
}
尝试使用''wifstream''和''wcout''。
Try using ''wifstream'' and ''wcout''.
1试过，它没有编译。
错误C2679：二进制''>>''：找不到右侧的运算符
类型''std :: string''的操作数（或者没有可接受的转换）
我还添加了wstring并且它编译但是它确实没有工作正常：它
会打印大量垃圾。
2我认为使用C ++可以完全使用
标准方式（避免特殊构造为wcout）可能设置一些
库选项。是不是真的？
非常感谢，K。
1 Tried, it doesn''t compile.
error C2679: binary ''>>'' : no operator found which takes a right-hand
operand of type ''std::string'' (or there is no acceptable conversion)
I added also wstring and it compile but it doens''t work correctly: it
prints a lot of garbage.
2 I thought that with C++ there was the possibility to use exactly the
standard way (avoid special construct as wcout) maybe setting some
library option. Is it not at all true?
Thanks a lot, K.

你应该使用wstring。 wchar_t字符串文字以L为前缀。例如：
wstring s = L" Some string" ;;

You should use wstring. A wchar_t string literal is prefixed with L. For example:
wstring s= L"Some string";

这些*是*标准设施。所有的字符串工具都带有他们的wchar_t等价物
（包括C子集的设施）。
