在Windows控制台应用程序中输出Unicode字符串 [英] Output unicode strings in Windows console app

问题描述

我发现这个： http://stackoverflow.com/questions/1922294/using-unicode-font-in-c-console-app\">在c ++控制台应用程序中使用unicode字体，此代码段可以工作。

  SetConsoleOutputCP（CP_UTF8）; 
 wchar_t s [] = LèéøÞǽлљΣæča; 
 int bufferSize = WideCharToMultiByte（CP_UTF8，0，s，-1，NULL，0，NULL，NULL）; 
 char * m = new char [bufferSize]; 
 WideCharToMultiByte（CP_UTF8，0，s，-1，m，bufferSize，NULL，NULL）; 
 wprintf（L％S，m）; 
  

然而，我没有找到任何方法正确输出unicode与iostreams。有任何建议吗？

这不起作用：

  SetConsoleOutputCP（CP_UTF8 ）; 
 utf8_locale = locale（old_locale，new boost :: program_options :: detail :: utf8_codecvt_facet（））; 
 wcout.imbue（utf8_locale）; 
 wcout<< L¡ << endl; 
  

EDIT
我找不到任何其他解决方案，将此代码段包裹在流中。
希望，有人有更好的想法。

  // Windows控制台的Unicode输出
 ostream& operator-（ostream& stream，const wchar_t * s）
 {
 int bufSize = WideCharToMultiByte（CP_UTF8,0，s，-1，NULL，0，NULL，NULL）; 
 char * buf = new char [bufSize]; 
 WideCharToMultiByte（CP_UTF8，0，s，-1，buf，bufSize，NULL，NULL）; 
 wprintf（L％S，buf）; 
 delete [] buf; 
 return stream; 
} 
 
 ostream& operator-（ostream& stream，const wstring& s）
 {
 stream  -  s.c_str 
 return stream; 
} 
  

解决方案

使用Visual Studio 2010.通过此 MSDN文章和 MSDN博客文章。窍门是对 _setmode（...，_O_U16TEXT）的模糊调用。

解决方案： / strong>

  #include< iostream> 
 #include< io.h> 
 #include< fcntl.h> 
 
 int wmain（int argc，wchar_t * argv []）
 {
 _setmode（_fileno（stdout），_O_U16TEXT）; 
 std :: wcout<< L测试unicode  - 英语 - Ελληνικά - Español。 << std :: endl; 
}

Hi I was trying to output unicode string to a console with iostreams and failed.

I found this: Using unicode font in c++ console app and this snippet works.

SetConsoleOutputCP(CP_UTF8);
wchar_t s[] = L"èéøÞǽлљΣæča";
int bufferSize = WideCharToMultiByte(CP_UTF8, 0, s, -1, NULL, 0, NULL, NULL);
char* m = new char[bufferSize]; 
WideCharToMultiByte(CP_UTF8, 0, s, -1, m, bufferSize, NULL, NULL);
wprintf(L"%S", m);

However, I did not find any way to output unicode correctly with iostreams. Any suggestions?

This does not work:

SetConsoleOutputCP(CP_UTF8);
utf8_locale = locale(old_locale,new boost::program_options::detail::utf8_codecvt_facet());
wcout.imbue(utf8_locale);
wcout << L"¡Hola!" << endl;

EDIT I could not find any other solution than to wrap this snippet around in a stream. Hope, somebody has better ideas.

//Unicode output for a Windows console 
ostream &operator-(ostream &stream, const wchar_t *s) 
{ 
    int bufSize = WideCharToMultiByte(CP_UTF8, 0, s, -1, NULL, 0, NULL, NULL);
    char *buf = new char[bufSize];
    WideCharToMultiByte(CP_UTF8, 0, s, -1, buf, bufSize, NULL, NULL);
    wprintf(L"%S", buf);
    delete[] buf; 
    return stream; 
} 

ostream &operator-(ostream &stream, const wstring &s) 
{ 
    stream - s.c_str();
    return stream; 
} 

解决方案

I have verified a solution here using Visual Studio 2010. Via this MSDN article and MSDN blog post. The trick is an obscure call to _setmode(..., _O_U16TEXT).

Solution:

#include <iostream>
#include <io.h>
#include <fcntl.h>

int wmain(int argc, wchar_t* argv[])
{
    _setmode(_fileno(stdout), _O_U16TEXT);
    std::wcout << L"Testing unicode -- English -- Ελληνικά -- Español." << std::endl;
}
